 36-117 2.91e-40

Immunoglobulin (Ig)-like domain of Cluster of Differentiation (CD) 3 epsilon chain; member of the C1-set of IgSF domains; The members here are composed of the immunoglobulin (Ig)-like domain of Cluster of Differentiation (CD) 3 epsilon chain. CD3 is a T cell surface receptor that is associated with alpha/beta T cell receptors (TCRs). The CD3 complex consists of one gamma, one delta, two epsilon, and two zeta chains. The CD3 subunits form heterodimers as gamma/epsilon, delta/epsilon, and zeta/zeta. The gamma, delta, and epsilon chains each contain an extracellular Ig domain, whereas the extracellular domains of the zeta chains are very small and have unknown structure. The CD3 domain participates in intracellular signaling once the TCR has bound an MHC/antigen complex.

 185-204 3.54e-03

Immunoreceptor tyrosine-based activation motif; T cell receptor (TCR) is a complex multi-protein cell surface receptor composed of the ligand-sensing TCR heterodimer and three signaling subunits. These signaling subunits contain cytoplasmic immunoreceptor tyrosine-based activation motifs (ITAMs) with a consensus sequence of YxxL/Ix6-12YxxL/I. The two tyrosines are phosphorylated by a Src kinase, Lck or Fyn. Binding of the dually phosphorylated ITAM peptide reorients the two SH2 domains relative to each other, destabilizing inhibitory interactions made by the linker connecting the SH2 and kinase domains.
