Abstract: A novel IFN-?/? independent ligand receptor system which upon engagement leads, among other things, to the establishment of an anti-viral state is disclosed. Further disclosed are three closely positioned genes on human chromosome 19 that encode distinct but highly homologous proteins, designated IFN-?1, IFN-?2, IFN-?3, based, inter alia, in their ability to induce antiviral protection. Expression of these proteins is induced upon viral infection. A receptor complex utilized by all three IFN-? proteins for signaling is also disclosed. The receptor complex is generally composed of two subunits, a novel receptor designated IFN-?R1 or CRF2-12, and a second subunit, IL-10R2 or CRF2-4, which is also a shared receptor component for the IL-10 and IL-22 receptor complexes. The gene encoding IFN-?R1 is generally widely expressed, including many different cell types and tissues. Expression of these proteins is induced by immune events, including, for example, upon viral infection.
