CD3E&D-310H |
Description : |
T-cell surface glycoprotein CD3 delta/epsilon chain, also known as CD3D and CD3E respectively, are single-pass type I membrane proteins. The genes encoding the epsilon, gamma and delta polypeptides are located in the same cluster on chromosome 11. CD3D, together with CD3- epsilon(CD3E) , CD3-gamma and CD3-zeta, and the T-cell receptor alpha/beta and gamma/delta heterodimers, forms the T cell receptor-CD3 complex. T cell receptor-CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. This complex is critical for T-cell development and function, and represents one of the most complex transmembrane receptors. The T cell receptor-CD3 complex is unique in having ten cytoplasmic immunoreceptor tyrosine-based activation motifs (ITAMs). The immunofluorescence defined that CD3 epsilon(CD3E0) was strongly stained bound to either CD 3 gamma or CD 3 delta. The recognition by this panel of anti-CD3 antibodies of CD3-gamma/ epsilon and CD3-delta/ epsilon complexes and not of CD3-epsilon alone was assessed by immunoprecipitation. |

Molecular Mass : |
The recombinant heterodimer of human CD3D/CD3E comprises 670 (333+354) amino acids and has a calculated molecular mass of 77.5 (37.5+40) KDa. As a result of glycosylation, the apparent molecular mass of human CD3D/CD3E heterodimer is approximately 45-50 KDa in SDS-PAGE under reducing conditions. |
