Definitions

  • the present invention provides novel polynucleotides which are expressed sequence tags (ESTs) for secreted proteins.
  • ESTs expressed sequence tags
  • Gargantuan efforts have been employed by various investigational projects to randomly sequence portions of naturally-occurring cDNAs.
  • the rationale behind this approach to identification and sequencing genes is founded in two basic principles: (1) that transcribed cDNAs represent the product of the most important genes, namely those that are actually expressed in vivo, and (2) that efforts to sequence genes and other portions of the genome of target organisms which are not actually expressed wastes substantial effort on areas not likely to yield genetic information of therapeutic importance.
  • the high-throughput sequencing efforts focus on only those portions of the genome which are expressed.
  • cDNA sequences represent "expressed sequence tags" or "ESTs”, which identify and can be used as probes for the longer, full-length cDNA or genomic sequence from which they were transcribed.
  • ESTs expressed sequence tags
  • This "shortcut" approach to genomic sequencing presents savings of effort compared to sequencing of the complete genome, it still produced a vast array of ESTs which may not be directly useful as protein therapeutics.
  • the majority of protein-related drug discovery has focused on the use of secreted proteins to produce a desired therapeutic effect.
  • 5,536,637 which is incorporated herein by reference, provides methods for focusing genomic sequencing efforts on sequences encoding the secreted proteins which are of most interest for identification of protein therapeutics.
  • the '637 patent discloses a "signal sequence trap" which selectively identifies ESTs for secreted proteins, namely "secreted expressed sequence tags” or "sESTs". It is to these sESTs that the present invention is directed.
  • the present invention provides for sESTs isolated from a variety of human RNA/cDNA sources.
  • the present invention provides an isolated polynucleotide comprising a nucleotide sequence selected from the group consisting of:

  • the invention also provides for proteins encoded by the above-described polynucleotides.
  • Each pair of entries in this table consists of the SEQ ID NO (e.g., 1 , 2, etc.) followed by the Clone ID No. for such sequence (e.g., Bl l, B18, etc.).
  • the "Clone ID No." for a particular clone consists of one or two letters followed by a number. The letters designate the tissue source from which the sEST was isolated. Table 3 below lists the various sources which were run through applicants' signal sequence trap. Thus, the tissue source for a particular sEST sequence can be identified in Table 3 by the one and two letter designations used in the relevant "Clone ID No. " . For example, a clone designated as "BA312" would have been isolated from a human placenta (26 yrs.) library (i.e., selectin "BA”) as indicated in Table 3.
  • polynucleotide includes single- and double-stranded RNAs, DNAs and RNA: DNA hybrids.
  • a "secreted” protein is one which, when expressed in a suitable host cell, is transported across or through a membrane, including transport as a result of signal sequences in its amino acid sequence.
  • "Secreted” proteins include without limitation proteins secreted wholly (e.g., soluble proteins) or partially (e.g. , receptors) from the cell in which they are expressed.
  • “Secreted” proteins also include without limitation proteins which are transported across the membrane of the endoplpasmic reticulum.
  • Fragments of the proteins of the present invention which are capable of exhibiting biological activity are also encompassed by the present invention.
  • Fragments of the protein may be in linear form or they may be cyclized using known methods, for example, as described in H.U. Saragovi, et al. , Bio/Technology IQ, 773-778 (1992) and in R.S. McDowell, et al. , J. Amer. Chem. Soc. Ji4, 9245-9253 (1992), both of which are incorporated herein by reference.
  • Such fragments may be fused to carrier molecules such as immunoglobulinsfor many purposes, including increasing the valency of protein binding sites.
  • fragments of the protein may be fused through "linker" sequences to the Fc portion of an immunoglobulin.
  • a fusion could be to the Fc portion of an IgG molecule.
  • Other immunoglobulin isotypes may also be used to generate such fusions.
  • a protein - IgM fusion would generate a decavalent form of the protein of the invention.
  • the present invention also provides both full-length and mature forms of the disclosed proteins.
  • the full-length form of the such proteins is identified in the sequence listing by translation of the nucleotide sequence of each disclosed clone.
  • the mamre form of such protein may be obtained by expression of the disclosed full-length polynucleotide (preferably those deposited with ATCC) in a suitable mammalian cell or other host cell.
  • the sequence of the mamre form of the protein may also be determinable from the amino acid sequence of the full-length form.
  • the present invention also provides genes corresponding to the cDNA sequences disclosed herein.
  • the corresponding genes can be isolated in accordance with known methods using the sequence information disclosed herein. Such methods include the preparation of probes or primers from the disclosed sequence information for identification and/or amplification of genes in appropriate genomic libraries or other sources of genomic materials.
  • the present invention also provides for soluble forms of such protein.
  • the intracellular and transmembrane domains of the protein are deleted such that the protein is fully secreted from the cell in which it is expressed.

  • Tolerance which involves inducing non-responsiveness or anergy in T cells, is distinguishable from immunosuppression in that it is generally antigen-specific and persists after exposure to the tolerizing agent has ceased. Operationally, tolerance can be demonstrated by the lack of a T cell response upon reexposure to specific antigen in the absence of the tolerizing agent.

Preventing the activation of autoreactive T cells may reduce or eliminate disease symptoms.
  • Administration of reagents which block costimulation of T cells by disrupting receptor :ligand interactions of B lymphocyte antigens can be used to inhibit T cell activation and prevent production of autoantibodies or T cell-derived cytokines which may be involved in the disease process. Additionally, blocking reagents may induce antigen-specifictolerance of autoreactive T cells which could lead to long-term relief from the disease.
