Background: CD3 epsilon

CD3 epsilon (T-Cell Surface Glycoprotein CD3 Epsilon) is a type I transmembrane protein that belongs to the Ig (Immunoglobulin) superfamily. Human CD3 epsilon consists of 104 amino acid (aa) extracellular domain, 26 aa transmembrane domain and 55 aa cytoplasmic domain (1). With the extracellular domain, human CD3 epsilon shares 44.2% and 49% homology with mouse and rat CD3 epsilon respectively. There are four CD3 proteins: CD3 delta, CD3 epsilon, CD3 gamma, and CD3 zeta. All CD3 proteins contain ITAM (Immunoreceptor Tyrosine-based Activation Motifs) in the cytoplasmic tail, which becomes phosphorylated by Src family protein tyrosine kinases LCK and FYN upon TCR engagement (2). CD3 proteins form heterodimers of CD3 delta /CD3 epsilon and CD3 gamma /CD3 epsilon, which bind to TCR and form trimeric TCR alpha /CD3 epsilon /CD3 gamma and TCR beta /CD3 gamma /CD3 epsilon. The resulting heterohexamer further associates with CD3 zeta homodimer and forms TCR/CD3 signaling complex (3, 4). Similar complex is also formed with TCR gamma and TCR delta (5). CD3 epsilon plays essential role in adaptive immune response. Mutations in CD3 epsilon lead to SCID (severe combined immunodeficiency) (6).
