IFN-alpha/beta R2: Products

IFN-alpha/beta R2, also known as IFNAR2, is a 100 kDa component of the class II cytokine receptor that binds the type I interferons IFN-alpha, IFN-beta, and IFN-omega. IFN-alpha/beta R2 associates with the 125 kDa IFN-alpha/beta R1 component to form a receptor complex that transmits antiviral and antiproliferative signals. Down-regulation of the receptor is accomplished by ubiquitination and degradation. A soluble form of the protein, corresponding to the extracellular ligand-binding domain, is generated by alternative splicing.
