Background

Interferon alpha-1, also named interferon alpha-D, is belonging to the type I interferon family and is encoded by the IFNA1gene in humans. Interferon alpha-1 is expressed in peripheral blood leukocytes and lymphoblastoid cells. IFNalpha-1 contains four highly conserved cysteine residues which form two disulfide bonds, one of which is necessary for biological activity. It plays an important role in inducing non-specific resistance against a broad range of viral infections, and also affects cell proliferation and modulates immune responses. IFNalpha-1a and IFNalpha-1b are two forms of interferon alpha-1 except for the substitution of alanine for valine at position 137. Interferon-alpha represents a group of related but distinct proteins that share over 95 % amino acid sequence homology.
