T-cell receptor gamma chain C region PT-gamma-1/2 is a protein that in humans is encoded by the TRG@ gene.T cell receptors recognize foreign antigens which have been processed as small peptides and bound to major histocompatibility complex (MHC) molecules at the surface of antigen presenting cells (APC). Each T cell receptor is a dimer consisting of one alpha and one beta chain or one delta and one gamma chain.
