IFN-gamma R1/CD119: Products

The high-affinity IFN-gamma receptor complex is made up of two type I transmembrane proteins, IFN-gamma R1 (IFN-gamma R alpha) and IFN-gamma R2 (IFN-gamma R beta). Both proteins are members of the type II cytokine receptor family. IFN-gamma R1 is the ligand-binding subunit that is necessary and sufficient for IFN-gamma binding and receptor internalization. IFN-gamma R2 is required for IFN-gamma signaling, but does not bind IFN-gamma by itself.
