T-Cell Surface Glycoprotein CD3 Gamma (CD3g)

CD3G (gamma chain) is one of the four peptides (gamma, delta, epsilon and zeta) that form CD3. Defects in CD3G are associated with T cell immunodeficiency.

T-Cell Surface Glycoprotein CD3 Gamma is the CD3-gamma polypeptide, which together with CD3-epsilon, -delta and -zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T-cell receptor-CD3 complex. This complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. Defects in this gene are associated with T cell immunodeficiency.
