IFN-R1 (L461) polyclonal antibody

The type I interferons, IFN-α and IFN-β, are a group of structurally and functionally related proteins that are induced by either viruses or double-stranded RNA and are defined by their ability to confer an antiviral state in cells. IFN-α and IFN-β appear to compete with one another for binding to a common cell surface receptor, while immune IFN (IFN-γ) binds to a distinct receptor. This distinct receptor, IFN-αR, is only weakly responsive to type I interferons, in contrast to IFN-α/βR, which binds to and responds effectively to IFN-β and to several of the IFN-α subtypes. IFN-α/βR is expressed as two alternatively spliced transcripts, designated IFN-α/βRα (IFN-α/βR1) and IFN-α/βRβ (IFN- α/βR2), both of which are involved in signal transduction and ligand binding.
