背景信息
CD3 is a complex of proteins that directly associates with the T cell receptor (TCR). The TCR/CD3 complex of T-lymphocytes consists of either a TCR alpha/beta or TCR gamma/delta heterodimer coexpressed at the cell surface with the invariant subunits of CD3 labeled gamma, delta, epsilon, zeta, and eta. The TCR recognizes antigens bound to major histocompatibility complex (MHC) molecules. TCR-mediated peptide-MHC recognition is transmitted to the CD3 complex, leading to the intracellular signal transduction. CD3 gamma/CD3G is a single-pass type I membrane protein which consists of an extracellular domain of 94 amino acids, a transmembrane region, and a cytoplasmic domain of 45 amino acids. In addition to this role of signal transduction in T-cell activation, CD3 gamma plays an essential role in the dynamic regulation of TCR expression at the cell surface.
