In vertebrate sensory systems, periph~ral neurons respond to environmental stimuli and transmit these signals to higher sensory centers in the brain where they are processed to allow the discrimination of complex sensory information.
The delineation of the peripheral mechanisms by which environmental stimuli are transduced into neural information can provide insight into the logic underlying sensory processing. Our understanding of color vision, for example, emerged only after the observation that the discrimination of hue results from the blending of information from only three classes of photoreceptors ~1, 2, 3, 4). The basic logic underlying olfactory sensory perception, however, has remained elusive. Mammals possess an olfactory system of enormous discriminatory power (5, 6). Humans, for example, ! are thought to be capable of distinguishing among thousands of distinct odors. The specificity of odor recognition is emphasized by the observation that subtle alterations in the molecular structure of an odorant can lead to profound '' '.. '' ''' ~.'' ~ ': .

W~9~/1758' PCT/US92/02741 ~ 6 8 ~ 7 ~

changes in perceived odor.

The detection of chemically distinct odorant presumably results from the association of odorous ligands with specific receptors on olfactory neurons which reside in a specialized epithelium in the nose. Since these receptors have not been identified, it has been difficult to determine how odor discrimination might be achieved. It is possible that olfaction, by analogy with color vision, involves only a few odor receptors, each capable of interaction with multiple odorant molecules. Alternatively, the sense of smell may involve a large number of distinct receptors each i-capable of associating with one or a small number of odorant. In either case, the brain must distinguish which receptors or which neurons have been activated to allow the discrimination between different odorant stimuli. Xnsight into the mechanisms underlying olfactory perception is likeLY to depend upon the i~olation of the odorant receptors, and the characterization of their diversity, specificity, and patterns of expression. -~

The primary events in odor detection occur in a specialized ol~actory neuroepithelium located in the posterior recesses o~ the nasal cavity. Three cell types dominate this epithelium (Figure lA)- the olfactory ~ensory neuron, the sustentacular or supporting cell, and the basal cell which is a stem cell that generates olfactory neurons throughout life (7, 8). The olfactory sensory neuron is bipolar: a dendritic process extends to the mucosal surface where it gives rise to a number of specialized cilia which provide an ;
extensivè, receptive surface for the interaction of odors with olfactory sensory neurons. The olfactory neuron also ;~
gives rise to an axon which projects to the olfactory bulb of the brain, the first relay in the olfactory system. The axons of the olfactory bulb neurons, in turn, project to :

WO92/1758' PCT/US~2/02741 ,~ ., subcortical and cortical ragions where higher l~vel processing of olfactory information allows the discrimination of odors by the brain.
.. .... .
5 The initial events in odor discrimination are thought to involve the association of odors with specific receptors on the cilia of olfactory neurons. Selective removal of the cilia results in the loss of olfactory response (9).
Moreover, in fish, whose olfactory system senses amino acids as odors, the specific binding of amino acids to isolated cilia has been demonstrated (10, 11). The cilia are also the site o~ olfactory signal transduction. Exposure of isolated cilia from rat ol~actory epithelium to numerous odorant leads to the rapid sti~ulation of adenylyl cyclase and elevations in cyclic AMP (an elevation in IP3 in response to one odorant has also b~en observed) (12, 13, 14, 15). The activation of adenylyl cyclase is dependent on ~he presence of GTP and is therefore likely to be mediated by receptor-coupled GTP binding proteins ~G-proteins) tl6~.
Elevations in cyclic AMP, in turn,~are thought to elicit depolarization o~ olfactory neurons by direct activation of a cyclic nucleotide-gated, cation permeable channel (17, 18). This channel i5 opened upon binding of cyclic nucleotides to its cytoplasmic domain, and can therefore transduce changes in intracellular levels of cyclic AMP into alterations in the membrane potential. ~-.:
These observations suggest a pathway for olfactory signal transduction (Figure lB) in which the binding of odors to specific surface receptors activates specific G-proteins.
The G-proteins then initiate a cascade of intracellular signalling events leading to the generation of an action potential which is propagated along the olfactory sensory axon to the brain. A number of neurotransmitter and hormone receptors which transduce intracellular signals by ,..~ ~:

activation of specific G-proteins have been identified.
Gene cloning has demonstrated that each of these receptors is a member of a large superfamily of surface recPptors which traverse the membrane seven times (19, 20). The S pathway of olfactory signal transduction (Figure lB) predicts that the odorant receptors might,also be members of this superfamily of receptor proteins. The detection of odors in the periphery is therefore likely to involve signalling mechanisms shared by other hormone or neurotransmitter systems, but the vast discriminat~ry power of the olfactory system will require higher order neural processing to permit the perception of individual odors.
This invention address the problem of olfactory perception at a molecular level. Eighteen different members of an extremely large multigene family have been cloned and characteri~ed which encodes seven transmembrane domain proteins whose expression is restricted to the olfactory epithelium. The members of this novel gene family encode ~ -the individual odorant receptors.

Figure 1. The Olfactor~ NeuFoepithelium and a Pathwav for Olfactorv Sianal Transduction. A. T h e O l f a c t o r y Neuroepithe}ium. The initial event in odor perception occurs in the nasal cavity in a specialized neuroepithelium which is diagrammed here. Odors are belie~ed to interact with specific receptors on the cilia of olfactory sensory neurons. The signal generated by these initial binding events are propagated by olfactory neuron axons to the olfactory bulb. B. A Pathway of Olfactory Signal Transduction. In this scheme, the binding of an odorant molecule to an odor-specific transmembrane receptor leads to the interaction of the receptor with a GTP-binding protein (Gs[olf~)~ This interaction, in turn, leads to the release of the GTP-coupled ~-subunit of the G-protein, which then stimulates adenylyl cyclase to produce elevated levels of cAMP. The increase in cAMP opens nucleotide-gated cation channels, thus causing an alteration in membrane potential.

Twenty-two of the 64 PCR products that were isolated and digested with Hinf I are shown here. Digestion of one of these, PCR

Amino acid residues which are conserved in 60~ or more of the proteins are shaded. The presence of seven hydrophobic domains (I-VII), as well as short conserved motifs shared with other members of the superfamily, demonstrate that these proteins belong to the seven transmembrane domain protein superfamily. Motifs ~;~
conserved among members of the superfamily and the family of olfactory proteins include the GN in TM1 (transmembrane domain 1), the central W of TM4, the Y near the C-terminal end of TM5, and the NP in TM7. In addition, the DRY motif C-terminal to TM3 is common to many members of the G-protein-coupled superfamily. Nowever, all of the proteins shown here share sequence motifs not found in other members of this superfamily and are clearly members of a novel family of proteins.

Rat Sequences used to obtain similar sequences exeressed ln Humans There are genes similar to the rat genes discussed above present in humans, these genes may be readily isolated by screening human gene libraries with the cloned rate sequences or by performing PCR experiments on human genomic DNA with primers homologous to the rat se~uences~ First, PCR experiments were performed with genomic DNA from rat, human, mouse, and several other species. When primers homologous to transmembrane domains 2 and 6 (the A4/B6 primer set used to isolate the original rat sequences) were used, DNA of the appropriate sizs was amplified from rat, human and mouse DNAs. When these primary PCR reactions were subsequently diluted and subjected to PCR using primers to internal sequences tPl and P4 primers), smaller DNA species were amplified whose size was that seen when the ~ame primers were used in PCR reactions with the cloned rat cDNAs. Similarly, when the secondary PCR was performed with one outer primer together with one inner primer (ie. ~4/P4 or P1/B6), amplified DNAs were obtained whose sizes were also consistent with the amplification~of genes similar in sequence and organization to the cloned rat cDNAs. Second, a mix of segments from 20 of the rat cDNAs ('P1" probe) was used to screen libraries constructed from human genomic DNAs. Hybridization under high or low stringency conditions reveals the presence of a large number of cloned human DNA
segments that are homologous to the rat sequences.

The inserted sequence in human clones H3/H5 was amplified by PCR with the A4/B6 primers, gel purified, and then labeled with 32P. The labeled DNA was then hybridizecl to restriction enzyme human placenta. Multiple hybridizing species were observed with each DNA (See Figure 32). This observation is consistent with the presence of a family of odorant receptor genes in the human genome.

The amplification products of each PCR reaction were then analyzed by agarose gel electrophoresis. Multiple bands were observed with each of the primer combinations.
The PCR products within the size range expected for this family of receptors ~600 to 1300 bp~ were subsequently picked and amplified further with the appropriate primer pair in order to isolate individual PCR bands. Sixty-four PCR bands isolated in this fashion revealed only one or a small number of bands upon agarose gel electrophoresis.
Representatives of these isolated PCR products are shown in Figure 2A.
The isolated PCR products were digested with the -~
endonuclease, Hae III or Hinf I, which recognize four base restriction sites and cut DNA at frequent intervals. In most instances, digestion of the PCR product with Hinf I
generated a set of fragments whose molecular weights sum to the size of the original DNA (Figure 2B). These PCR bands are therefore likely to each contain a single DNA species.
In some cases, however, restriction digestion yielded a series of frasments whose molecular weights sum to a value greater than that of the original PCR product. The most dramatic example is shown in Figure 2 where the 710 bp, PCR
13 DNA, is cleaved by Hinf I to yield a very large number of restriction fragments whose sizes sum to a value five- to ten-fold greater than that of the original PCR product.
These observations indicated that PCR product 13 consists of a number of different species of DNA, each of which could be amplified with the same pair of primer oligonucleotides.

In order to determine whether the multiple DNA species preisent in PCR 13 encode members of a family of seven transmembrane domain proteins, PCR 13 DNA was cloned into the plasmid vector Bluescript and five individual clones were subjected to DNA sequence analysis. Each of the five clones exhibited a different DNA sequence, but each encoded a protein which displayed conserved features of the superfamily of seven transmembrane domain receptor proteins~
In addition, the proteins encoded by all five clones shared distinctive sequence motifs not found in other superfamily members indicating they were all members of a new family of receptors.

To obtain full-length cDNA clones, cDNA libraries prepared ;~-from olfactory epithelium RNA or from RNA of an enriched population of olfactory sensory neurons were screened. The probe used in these initial screens was a mixture of PCR 13 DNA as well as DNA obtained by amplication of rat genomic DNA or DNA from two olfactory cDNA libraries with the same pri~ers used to generate PCR 13 (A4 and B6 primers). :
Hybridizing plaques were subjected to PCR amplification with the A4/B6 primer set and only those giving a PCR product of the appropriate size ~approximately 710 bp) were purified.

The original pair of primers used to amplify PCR 13 DNA were then used to amplify coding segments of 20 different cDNA
clones. A mix of these PCR products were labeled and used as prob~ for further cDNA library screens. This mixed probe was also used in a Northern blot ~Figure 3) to determine whether the expression of the gene family is restricted to the olfactory epithelium. The mixed probe detects two diffuse bands centered at 2 and 5 kb in RNA from olfactory }5 epithelium; no hybridization can be detected in brain or spleen. (Later experiments which examined a larger number of tissue RN~5 with a more restricted probe will be shown below.) Taken together, these data indicate the discovery of a novel multigene family encoding seven transmembrane domain proteins which are expressed in olfactory epithelium, and could be expressed predominantly or exclusively in olfactory neurons.

The Protein Se~uences of Numerous, OlfactorY-specific Members af the Seven Transmembrane Domain Superfamily Numerous clones were obtained upon screening cDNA libraries constructed from olfactory epithelium and olfactory neuron RNA at high stringency. Partial DNA sequences were obtained from 36 clones; 18 of these cDNA clones are different, but all of them encode proteins which exhibit shared sequence motifs indicating that they are members of the family identified in PCR 13 DNA. A complete nucleotide sequence was determined for coding regions of ten of the most 39 d~vergent clones (Figure 4). 1he deduced protein sequences ~

2 ~0~7 --2~-of these cDNAs defines a new multigene family which shares seguence and structural propertie~ with the superfamily of neurotransmitter and hormone receptors khat traverse the membrane seven times. This novel family, however, exhibit~
features different from any other member of the receptor superfamily thus far identified.
:: ' Each of the ten sequences contains seven hydrophobic stretches (19-26 amino acids) that represent potential transmembrane domains. These domains con~titute the regions of maximal sequence similarity to other members of the seven transmembrane domain superfamily (see legend to Figure 4).
On the basis of structural homologies with rhodopsin and the B-adranergic receptors, (19) it is likely that the amino termini of the olfactory proteins are located on the extracellular side of the plasma membrane and the carboxyl termini are located in the cytoplasm. In this scheme, three extracellular loops alternate with three intracellular loops to link the seven transmembrane domains (see Figure 5).
Analysis of the sequences in figure 4 demonstrates tha~ the ~-olfactory proteins, like other members of the receptor superfamily, display no evidence of an N-terminal signal sequence. As in several other super~amily members, a potential N-linked glycosylation site is present in all ten proteins within the~short N-terminal extracellular segment.
Other structural features conserved with previously identified members of the superfamily included cysteine residues at fixed positions within the ~irst and second extracellular loops that are thought to form a disulfide bond. Finally, many of the olfactory proteins reveal a conserved cysteine within the C-terminal domain which may serve as a palmitoylation site anchoring this domain to the membrane (21). These features, taken together with several short, conserved sequence motifs (see legend to Figure 4~, clearly define this new family as a member o~ tbP

superfamily of genes encoding the seven transmembrane domain recaptors.

There are, however, important differences between the olfactory protein family and the other seven transmembrane domain proteins described previously and these differences may be relevant to proposed function of these proteins in odor recognition. Structure-function experiments involving ln vitro mutayenesis suggest that adrenergic ligands interact with this class of receptor molecule by binding within the plane of the membrane (22, 20). Not surprisingly, small receptor families that bind the same class of ligands, such as the adrenergic and muscarinic acetylcholine receptor families exhibit ~aximum sequence conservation (often over 80%) within the transmembrane domains. In contrast, the family of receptors discussed in this application shows striking divergence within the third, fourth, and fifth transmembrane domains (Figure 4). The variability in the three central transmembrane domains is highlighted schematically in Figure 5. The divergence in potential ligand binding domains is consistent with the idea ~hat the family of molecules cloned is capable of associating with a large number of odorant of diverse molecular structure.
Receptors which belong to the superfamily of seven transmembrane domain proteins interact with G-proteins to generate intracellular signals. In _tro mutagenesis experiments indicate that one site of association between ~0 receptor and G-protein resides within the third cy~oplasmic loop (22, 23). The sequence of this cytoplasmic loop in 18 different clones we have characterized is shown in Figure 6A. This loop which is often quite long and of variable length in the receptor superfamily is relatively short (only 17 amino acids) and of fixed length in the 18 clones ~ ' ",, :.

examined. Eleven of the 18 different clones exhibit the sequence motif K/R I V S S I (or a close relative) at the N-terminus of this loop. Two of the cDNA clones reveal a different H I T C/W A V motif at this site. If this short loop is a site of contact with G-proteins, it i~ii possible that the conserved motifs may reflect sites of interaction with different G-proteins that activate different intracellular signalling systems in response to odors. In addition, the receptors cloned reveal several serine or threonine residues within the third cytoplasmic loop. By analogy with other G-protein coupled receptors, these residues may represent sites of phosphorylation for specific receptor kinases involved in desensitization. (24) Subfamilies within the Multiqene Family ..
Figure 6A displays the sequences of the fifth transmembrane domain and the adjacent cytoplasmic loop encoded by L8 of the cDNA clones we have analyzed. As a group, the 18 sequences exhibit considerable divergence within this region. The multigene family, however, can be divided into subfamilies such that the members of a given subfamily share significant sequence conservation. In subfamily B, clones F12 and F13, for example, differ from one another at only four of 44 positions (91~i identify), and clearly define a subfamily. Clones F5 and Ill (subfamily D) differ from F12 and F13 at 34-36 positions within this region and clearly define a separate subfamily. Thus, this olfactory-specific multigene family consists of highly divergent subfamilies.
If these genes encode odor receptors, i~ is possible that members of the divergent subfamilies bind odorant of widely differing structural c~lasses. Members of the individual subfamiIies could therefore recognize more subtle dif~erences between molecules which belong to the same ~ -structural class of molecules structures. ~

W092/l758~ PCT/US92/0~741 The Size of the Multiqene Family Genomic Southern blotting experiments were preformed and genomic libraries were screened to obtain an estimate o~ the sizes of the multigene ~amily a~d the member ~ubfamilie6 encoding the putative odor receptors. DNAs extending from the 3' end of transmembrane domain 3 to the middle of transmembrane domain 6 were synthesized by PCR from DNA of seven of the divergent cDNA clones (Figure 4). In initial experiments, these DNAs were labeled and hybridized to each other to define conditions under which minimal crosshybridization would be observed among the individual clones. At 70C, the seven DNAs showed no crosshybridization, or crosshybridized only very slightly.
The trace levels of crosshybridization observed are not likely to be apparent upon genomic Southern blot analysis where the amounts of DNA are far lower than in the test cross.

Probes derived from these seven DNAs were annealed under stringent conditions, either individually or as a group, to Southern blots of rat liver DNA digested with the restriction endonucleases Eco RI or Hind III (Figure 7).
Examination of the Southern blots reveals that all but one o~` the cDNAs detects a relatively large, distinctive array of bands in genomic DNA. Clone I15 (probe 7), for example, detects about 17 bands with each restriction endonuclease, whereas clone F9 (probe 1) detects only about 5-7 bands with each enzyme. A single band is obtained with clone I7 (probe 5~. PCR experiments using nested primers ~TM2/TM7 primers followed by primers to internal sequences) and genomic DNA
as template indicate that the coding regions of the members of this multigene family, liXe those of many members of the G-protein coupled superfamily, may not be interrupted by ~ -35 ~ introns. This observation, together wit~ the fact that most ~ :"--, WO92/1758' PC~/US92/02741 2 ~ 7 ` - `

of the probes only encompasse6 400 nucl~otides suggests that aach band observed in these e~periment~ is likely to represent a different ~ene. These data sugge~t that the individual probes chosen are representatives of subfamilies which range in size from a ~ingle member to as many as 17 members. A total of about 70 individual bands were detected in this analysis which could represent the presence of at least 70 different genes. Although the DNA probes u~ed in these blots did not crosshybridize appreciably with each other, it is possible that a given gene might hybridize to more than one probe, resulting in an overestimate of gene number. However, it is probable that the total number of bands on].y reflects a minimal estimate of gene number since it is unlikely that we have isolated representative cDNAs from all of the potential subfamilies and the hybridizations were performed under conditions of very high stringency.

A more accurate estimate of the size of the olfactory-specific gene family was obtained by screening rat genomic libraries. The mix of the seven divergent probes used in Southern blots, or the mix of 20 different probes used in our initial Northern blots (see Figure 3), were used as hybridization probes under high (65C) or lowered (55C) stringency conditions in these experiments. Nested PCR ~see above) was used to verify that the clones giving a positive siqnal under low stringency annealing conditions were indeed members of this gene family. It is estimated fr~m these studies that there are between 100 and 200 positive clones per haploid genome. The estimate of the size of the family obtain from screens of genQmic libraries again represents a lower limit. Given the si~e of the multigene family, one might anticipate that many of these genes are linked such that a given genomic clone may contain multiple genes. Thus the data from Southern blotting and screens of genomic libraries indicate that the multigene family identified . .

~092/17~8~ 2 ~ 7 PCT/US92/02741 consists of one to several hundred member genes which can be divided into multiple subfamilies.
.
It should be noted that the cDNA probes isolated may not be representative of the full complement of subfamilies within the larger family of olfactory proteins. The isolation of cDNAs, for example, relies heavily on PCR with primers from transmembrane domains 2 and 7 and biases our clones for homology within these regions. Thus, estimates of gene number as well as subsequent estimates of RNA abunclance should be considered as minimal.

Expression of the Members of this Multi~ene Familv Additional Northern blot analyses were preformed to demonstrate that expression of the members o~ this gene family is restricted to the olfactory epithelium. (Figure 8) Northern blot analysis with a mixed probe consisting of the seven di~ergent cDNAs u~ed above reveals two diffuse bands about 5 and 2 kb in length in olfactory epithelium RNA.
This pattern is the same as that seen previously with the mix of 20 DNAs. No annealing is observed to RNA from the brain or retina or other, nonneural tissues, including lung, liver, spleen, and kidney.
An ~stimate of the level of expression of this family can be obtained from screens of cDNA libraries. The frequency of positive clones in cDNA libraries made from olfactory epithelium RNA suggests that the abundance of the RNAs in the epithelium is about one in 20,000. The frequency of positive clones is approximately five-fold higher in a cDNA
library prepared from RNA from purified olfactory neurons (in which 75% of the cells are olfactory neurons). The increased frequency of positive clones obtained in the olfactory neuron cDNA library is compar~ble to the .

These observation~ suggest that this multigene ~amily is expressed largely, if not solely, in olfactory neurons and may not be expressed in other cell types with.in the epithelium. If each ol~actory neuron contains 105 ~RN~
molecules, from the frequency of positive clones we predict that each neuron contains only 25-30 txanscripts derived from this gene family. Since the family of olfactory proteins consists of a minimum of a hundred genes, a given olfactory neuron could maximally express only a proportion of the many different family members. These values thus suggest that olfactory neurons will exhibit signif:icant diversity at the level of expression of these olfactory proteins.
Identification of ~heromone receptors in vomeronasal oraan The vomeronasal organ (vomeronasal gland) is an accessory olfactory structure that is located near the nasal cavity.
Like the olfactory epithelium of the nasal cavity, the olfactory epithelium of the vomeronasal organ contains olfactory sensory neurons. The vomeronasal organ is believed to play an important role in the sensing of pheromones in numerous species. Pheromones are believed to have profound effects on both physiol~gical and behavioral aspects of reproduction. the identification oP pheromone receptors would permit the identification of the pheromones themselves. It would also enable one to identify agonists or antagonists that would either mimic the pheromones or block the pheromone receptors from transducing pheromone signals.
Such information wouId be important to the development of species specific pesticides and, conversely, to animal husbandry. The identification of pheromone receptors in human could ultimately lead to the development of contraceptives or to treatments for infertility in humans.
It is likely that the identification of pheromone receptors WO92/1758' PCT/US92/02741 ~ 21~6~7 in low mammals such as rodents would lead to the identification of simil,r receptors in human.

DISCUSSION
.' ,':~
The mammalian olfactory system can recognize and discriminate a large number of odorous molecules~ -Perception in this system, as in other s~nsory systems, ..

-" . :' :' ~'092/l7~ 2 i a ~ ~ ~ 7 PCT/US92/0~741 ~. . , The odorant receptors are thought to transduce intracellular signals by interacting with G-proteins which activate second messenger systems (12, 13, 14, 15). These proteins are clearly members of the family of G-protein coupled receptori which traverse the membrane seven times (19~. The odorant receptors should be expressed specifically in the tissue in which odorant are recognized. The family of olfactory proteins cloned is exprecised in the olfactory ~pithelium.
~ybridizing RNA is not detected in brai~ or retina, or in a lo host of nonneural tissues. Moreover, expression of this gene family the epithelium may be restricted to olfactory neurons. The ~amily of odorant receptors must be capable of interacting with extremely diverse molecular structures.
The genes cloned are members of any extremely large multigene family which exhibit variability in regions thought to be important in ligand binding. The possibility that each member of t~is large family of seven transmembrane proteins is capable of interacting with only one or a small number of odorant provides a plausible mechanism to accommodate the diversity of odor perception. The properties of the gene family identified suggests that this family is likely to encode a large number of distinot odorant receptors.

Size of the Multiqene Familv The size of the receptor repertoire is likely to reflect the range of detectable odors and the degree of structural specificity exhibited by the individual receptors. It has been estimated that humans can identify ov~r lO,OOO
structurally-distinct odorous ligands. However, this does not nececsarily imply that humans possess an equally large repertoire of odorant receptors. For example, binding studies in lower vertebrates suggest that structurally-related odorant may activate the same receptor molecules.

WO92/17~X~ 2 ~ a ~ 8 ~ 7 PCT/US92/02741 In fish which smell amino acids, the binding of alanine to isolated cilia can be competed by other small polar residues (threonine and serine), but not by the basic amino acids, lysine or arginine (ll). These data suggest that individual receptors are capahle of associatinlg with several structurally-related ligands, albeit with different affinities. Stereochemical models of olfactory recognition in mammals (25) (based largely on psychophysical, rather than biophysical data) have suggested existence of several primary odor groups including camphoraceous, musky, peppermint, ethereal, pungent, and putrid. In such a model, each yroup would contain odorant with common molecular configurations which bind to common receptors anA share similar odor qualities.
Screens of genomic libraries with mixed probes consisting of divergent family members detect approximately lO0 to 200 positive clones per genome. The present estimate of at least lO0 genes provides only a lower limit since it is likely that the probes used do not detect all of the possible subfamilies. Moreover, it is probable that many of these genes are linked such that a given genomic clone may contain multiple genes. It is therefore expected that the actual size of the gene fami]y may be considerably higher and this family of putative odorant receptors could constitute one of the largest gene families in the genome.

The characterization of a large multigene family encoding putative odorant receptors suggests that the olfactory system utilizes a far greater number of receptors than the visual system. Color vision, for example, allows the discrimination of several hundred hues, but is accomplished by only three different photoreceptors (l, 2, 3 and 4). The photoreceptors each have different, but overlapping 35~ absorption spectra which cover the entire spectrum of :
.~

W092/l7~8~ PCT/~S9~/02741 7 ~

visible wavelengths. Discrimination of color reiults from comparative processing of the information from these three classes of photoreceptors in the brain. Whereas three photoreceptors can absorb light across the entire visible spectrum, our data suggest that a ~mall number of odorant receptors cannot recognize and disicriminate the full spectrum of distinct molecular structures perceived by the mammalian olfactory system. R~ther, olfactory perception probably employs an extremely large number of receptors each capable of recognizing a small number of odorous ligands.

Diver ity within the Gene FamilY and the Specificity of_Odor Recoqnition The olfactory proteins identified in this application are clearly members of the superfamily of receptors which traverse the membrane seven time. Analysis of the proteins encoded by the 18 distinct cDNAs we have cloned reveals structural features which may render this family particularly well suited for the detection of a diverse array of structurally distinct odorant. Experiments with other members of this class of receptors suggest that the ligand binds to its receptor within the plane of the membrane such that the ligand contacts many, if not all of the transmembrane helices. The family of olfactory proteins can be divided into several different subfamilies which exhibit significant sequence divergence within the transmembrane domains. Nonconservative changes are commonly observed within blocks of residues in transmembrane regions 3, 4, and 5 (Figures 4, 5, 6); these blocks could reflect the sites of direct contact with odorous ligands. Some members, for example, have acidic residues in transmembrane domain 3, which in other families are thought to be essential for binding aminergic ligands (20) while other members maintain hydrophobic residues at these positions.
'' ' .
.

W092/17~ PCT/US92/02741 2~68~7 This divergence within transmembrane dDmain6 may reflect the fact that the members of the ~amily of odorant receptors must associate with odorant of widely diffarent molecular structures.
These observations suggest a model in which each of the individual subfamilies encode receptors which bind distinct structural classes of odorant~ Within a given subfamily, however, the sequence differenoes are far less dramatic and are often restricted to a small number of residues. Thus, the members of a subfamily may recognize more subtle variations among odor molecules of a given structural class.
At a practioal level, individual subfamilies may recogni~e grossly different structures isuch that one subfamily may associate, for example, with the aromatic compound, benzene and its derivatives, whereas a second subfamily may recognize odorous, short chain, aliphatic molecules. Subtle variations in the structure of the receptors within, for --example, the hypothetical benzene subfamily could facilitate the recognition and discrimination of various substituted derivatives such as toluene, xylene or phenol. It should be noted that such a model, unlike previous stereochemical models, does not necessarily predict that molecules with similar structures will have similar odors. The activation of distinct receptors with similar structures could elicit different odors, since perceived odor will depend upon higher order processing of primary sensory information.

Evolution of the Gene Familv and the Generation of Diversi~y Preliminary evidence from PCR analyses suggests that members of this family of olfactory proteins are conserved in lower vertebrates as well as invertebrates. This gene family ~;~

odorant. Examination of the sequences of the family members cloned from mammals provides some insight into the evolution of this multigene family. Although the chromosomal locî
encoding these genes has yet to be characterized, it is likely that at least some member genes will be tandemly arranged in a large cluster as is observed with other large multigene families. A tandem array of t~is sort provides a template for recombination events including unequal crossing over and gene conversion, that can lead to expansion and further diversification of the sort apparent among the family members we have cloned (26).

The multigene family encoding the olfactory proteins is large: all of the member genes clearly have a common ancestral origin, but have undergone considerable divergence such that individual genes encode proteins that share from 40-80% amino acid identity. Subfamilies are apparent with groups of genes sharing greater homology among themselves than with members of other subfamilies. Examination of th~
sequences of even the most divergent subfamilies, however, reveals a pattern in which several blocks of c~nserved residues are interspersed with variable regions. This segmental homology is conceptually similar to the organization of framework and hypervariable domains within the families of immunoglobulin and T cell receptor variable region sequences (27, 2~). This analogy goes beyond structural organization and may extend to the function of these two gene families: each family consists of a large number of genes which have diversified over evolutionary time to accommodate the binding of a highly diverse array of ligands. The evolutionary mechanisms responsible for the diversification and maintenance of ~hese large gene families ~may also oe similar. It has been sugges~ed that gene conversion has played a major role in the evolution of immunoglobulin and T cell receptor variable domains (29, 30 -: ; :'':, '.

and 31). Analysis of the sequence of the putative olfactory receptors reveals at least one instance where a motif from a variable region of one subfamily is found imbedded in the otherwi~e divergent ~equence o~ a second subfamily, suggesting that conversion has occurr~d. Such a mixing o~
motifs from one subfamily to another over evolutionary time would provide additional combinatorial pos~sibilities leading to the generation of diversity.

It should be noted, however, that the combinatorial joining of gene segments by DNA rearrangement during development, which is characteristic of immunoglobulin loci (27), is not a feature of the putative odor receptor gene family. No evidence for DNA rearrangement to generate the diversity of genes cloned has been observed. The entire coding region has been sequenced along with parts of the 5' and 3l untranslated regions of 10 different cDNA clones. The sequences of the coding regions are all different; no evidence has been obtained for constant regions that would suggest DNA rearrangement of the sort seen in the immune system.

gene seguences.
.
Although it is unlikely from the data that DNA rearrange~ent is responsible for the generation of diversity among the putative odorant receptors, it remains possible that DNA
rearrangements may be involved in the regulation of expression of this gene family. If each olfactory neuron expresses only one or a small number of genes, then a transcriptional control mechanism must be operative to choose which of the more than one hundred genes within the family will be expressed in a given ne~ron. ~ene conversion from one of multiple silent loci into a single active locus, as observed for the trypanosome-variable surf ace . .

W092/17~8~ PCT/US92tO2741 2 ~ 7 glycoproteins (32), provides one attractive model. The yene conversion event could be stochastic, such that a given neuron could randomly express any one of several hundred receptor genes, or regulated (perhaps by positional information), such that a given neuron could only express one or a small number of predetermined receptor types.
Alternatively, it is possible that positional information in the olfactory epithelium controls the expression of the family of olfactory receptors by more classical mechanisms that do not involve DNA rearrangement. What ever mechanisms will regulate the expression of receptor genes within this large, multigene family, these mechanisms must accommodate the requirement that ol~actory neurons are regenerated every 30~60 days (8) and therefore the expression of the entire repertoire of receptors must be accomplished many times duri~g the life of an organism.

Receptor Diversity and_the Central Processina of Olfactory Information The results suggest the existence of a large family of distinct odorant receptors. Individual members of this receptor family are likely to be expressed by only a sm~ll set of the total number of olfactory neurons. The primary sensory ~eurons within th~ olfactory epithelium will therefore exhibit significant diversity at the level of receptor expression. The question then emerges as to whether neurons expressing the same receptoss are localized in the olfactory epithelium. Does the olfactory system employ a topographic map to discriminate among the numerous odorant? The spatial organization of distinct classes of olfactory sensory neurons, as defined by receptor expression, can now be determined by using the procedures of in situ hybridization and i~munohistochemistry with probes ~ 35 specific for the individual receptor subtypes. This ~;

WO 92/1758~ 2 1 ~ 6 ~ L~ 7 PCT/US92/02741 ~41--information should help to distinguish between different models that have b0en proposed to explain the coding of diverse odorant stimuli ~33).

In one model, sensory neurons that express a given receptor and respond to a given odorant may be localized within defined positions within the olfactory epithelium. This topographic arrangement would al50 be reflec~ed in the projection of olfactory sensory axons into discrete regions (glomeruli) within the olfactory bulb. In this scheme, the central coding to permit the discrimination of discrete odorant would depend, in part, on the spatial segregation of different receptor populations. Attempts to discern the topographic localization of specific receptors at the level of the olfactory epithelium has led to conflicting results.
In some studies, electrophysiological recordings have -revealed differences in olfactory re~ponses to distinct -~
odorant in different reyions of the olfactory epithelium (34, 35). However, these experiments have been difficult to interpret since the differences in response across the epithelium are often small and are not observed in all studies (36).

A second model argues that sensory neurons expressing distinct odorant receptors are randomly distributed in the epithelium but that neurons responsive to a given odorant project to restricted regions within the olfactory bulb. In this instance, the discrimination of odors would be a consequence of the position of second order ne.urons in the olfactory bulb, but would be independent of the site of origin of the afferent signals within the epithelium.
Mapping of the topographic projections of olfactory neurons has been performed by extracellular recordings from different regions of the bulb (37, 38) and by 2-deoxyglucose ~ -autoradiography to map regional activity after exposure to :
,:''.', :'., .. ..
',', ', ' : ~ , WO92/1758~ 2 ~ PCT/US9~/02741 ~,,1 ., diffe.rent odorant (39). These studies suggest that spatially localized groups of bulbar neur~ns preferentially respond to different odorant. The existence of specific odorant receptors, randomly distributed through the olfactory epithelium, which converge on a common target within the olfactory bulb, would raise additional questions about the recognition mechanisms usecl to guide these distinct axonal subsets to their central targets.

Other sensory systems also spatially segregate afferent input from primary sensory neurons. The spatial segregation of information employed, for example, ~y the visual and somatosensory systems, is used to define the location of the stimulus within the external environment as well as to indicate the quality of the stimulus. In contrast, olfactory processing does not extract spatial features of the odorant stimulus. Relieved of the necessity to encode information about the spatial localization of the sensory stimulus, it is possible that the olfactory system of mammals uses the spatial segregation of sensory input ~olely to enco~e the identity of the stimulus itself. The molecular identification of the genes likely to encode a large family of olfactory receptors should provide initial insights into the underlying logic of olfactory processing in the mammalian nervous system.
