Description

Details

Interferon-beta (IFN-b) is a member of the type I family of interferons, also including IFN-alpha and IFN-omega. These three interferons share a common cell surface receptor, INFAR, involved in both ligand binding and signal transduction. IFN-b has antiviral, antibacterial and anticancer activities and has been used as a treatment for multiple sclerosis. Proteins of this family also affect cell proliferation and modulate immune responses.
