Human<unk>  I interferons comprise a vast and growing group of IFN proteins.
All<unk>  I IFNs bind to a specific cell surface receptor complex known as the IFN-α receptor (IFNAR) that consists of IFNAR1 and IFNAR2 chains.
Homologous molecules to<unk>  I IFNs are found in many species, including most mammals, and some have been identified in birds, reptiles, amphibians and fish species.
