Interferon-αInterferon-βis a protein growth factor that stimulates an antiviral defense. Its encoding gene is one of only two known vertebrate structural genes that lacks introns.[2] Interferon-β is a relatively simple biological response modifier, with several . It consists of five , as well as multiple interconnecting . Helices A, B and D run , and helices C and E run to the other three helices, but to one another. Helix A consists of residues 6-23; Helix B consists of residues 49-65; Helix C consists of residues 77-91; Helix D consists of residues 112-131; and Helix E consists of residues 135-155.[3][4] Interferon-γ |
