Description:

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. 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.
