Interferon alpha-2 is a protein that in humans is encoded by the IFNA2 gene.
Interferon α2 within its family
Human interferon alpha-2 (IFNα2) is a cytokine belonging to the family of type I IFNs. IFNα2 is a protein secreted by cells infected by a virus and acting on other cells to inhibit viral infection. The first description of IFNs as a cellular agent interfering with viral replication was made by Alick Isaacs and Jean Lindenmann in 1957. The history of this finding was recently reviewed. There are 3 types of IFNs: Interferon type I, Interferon type II and Interferon type III. The type II IFN, also called IFNγ, is produced by specific cells of the immune system. Unlike type I and type III IFNs, IFNγ has only a modest role in directly restricting viral infections. Type I and type III IFNs act similarly. However, the action of type III IFNs, also known as IFNλ, is limited to epithelial cells while type I IFNs act on all body's cells.
Type I IFNs form a family of several proteins: in humans, there are 13 α subtypes, 1 β subtype, 1 ω subtype and other less studied subtypes (κ and ε). IFNα2 was the first subtype to be characterized in the early eighties. As a result, IFNα2 was widely used in basic research to elucidate biological activities, structure and mechanism of action of type I IFNs. IFNα2 was also the first IFN to be produced by the pharmaceutical industry for use as a drug. Thereby, IFNα2 is the best known type I IFN subtype. The properties of IFNα2 are widely shared by the other type I IFNs, although subtle differences exist.
