IFN alpha 1a (Interferon alpha 1a), Mouse
Interferon alpha-1 or interferon alpha-D, encoded by the human IFNA1gene, is a member of the type I interferon family . It is expressed in peripheral blood leukocytes and lymphoblastoid cells. There are four highly conserved cysteine residues which form two disulfide bonds. One bond is a necessity for biological activity, which plays an critical role in conducting non-specific resistance against a variety of viral infections, and regulation of cell proliferation and modulates immune responses.
