CD3e molecule, epsilon

CD3epsilon, CD3E
The protein encoded by this gene is the CD3-epsilon polypeptide, which together with CD3-gamma, -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. The epsilon polypeptide plays an essential role in T-cell development. Defects in this gene cause immunodeficiency. This gene has also been linked to a susceptibility to type I diabetes in women. [provided by RefSeq, Jul 2008] (from NCBI)

UNASSIGNED: We previously reported that Cd3e-deficient mice adoptively transferred with CD4(+) T cells generate high numbers of T follicular helper (Tfh) cells, which go on to induce a strong B-cell and germinal center (GC) reaction.

Call et al., Boston, United States. In Cold Spring Harb Perspect Biol, 2010
The intrinsic binding of the cytoplasmic domains of the CD3epsilon and zeta chains to the inner leaflet of the plasma membrane represents a novel mechanism for control of receptor activation: Insertion of critical CD3epsilon tyrosines into the hydrophobic membrane core prevents their phosphorylation before receptor engagement.
