IFN-omega is a type I interferon, which can be induced by virus-infected leukocytes. Members of the type I interferon family, which includes IFN-a, IFN-b, and IFN-omega, signal through IFNAR-1/IFNAR-2 receptor complex, and exert antiviral and antiproliferative activities. IFN-omega exhibits about 75% sequence homology with IFN-a, and contains two conserved disulfide bonds, which are necessary for full biological activity.
