CD3 epsilon Recombinant Protein

T-Cell Surface Glycoprotein CD3 epsilon Chain (CD3 epsilon) is a single-pass type I membrane protein. CD3 epsilon contains 1 Ig-like (immunoglobulin-like) domain and 1 ITAM domain. CD3 epsilon is a polypeptide encoded by the CD3E gene on chromosome 11 in humans. The T cell receptor-CD3 complex (TCR/CD3 complex) is involved in T-cell development and 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) . TCR/CD3 complex plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways.

Lyophilized from a 0.2 um filtered solution of PBS, pH7.4. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in ddH2O.
