NCIt definition : A heterodimeric complex comprised of the T-cell receptor gamma and delta chain proteins,
which are linked by interchain disulfide bonds. This membrane bound complex is expressed
on the surface of a small percentage of T-lymphocytes and is involved in the recognition
of antigenic lipids, peptide antigens, and peptides presented by major histocompatibility
(MHC) proteins. The gamma/delta dimer associates with the CD3 protein complex, which
promotes ligand-dependent signaling.;
