靶點(diǎn)詳情

功能：

Part of the TCR-CD3 complex present on T-lymphocyte cell surface that plays an essential role in adaptive immune response. When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain. Upon TCR engagement, these motifs become phosphorylated by Src family protein tyrosine kinases LCK and FYN, resulting in the activation of downstream signaling pathways. In addition of this role of signal transduction in T-cell activation, CD3E plays an essential role in correct T-cell development. Initiates the TCR-CD3 complex assembly by forming the two heterodimers CD3D/CD3E and CD3G/CD3E. Participates also in internalization and cell surface down-regulation of TCR-CD3 complexes via endocytosis sequences present in CD3E cytosolic region.

6. Data suggest that HIV-1 gp41 transmembrane domain (TMD) directly interacts with TMDs of the T-cell receptor and it's CD3-antigen co-receptors (delta, gamma, and epsilon); these interactions appear to be involved in immune evasion mechanism of HIV-1. PMID: 26828096

17. The CD3 epsilon immune recognition receptor cytoplasmic domain binds to acidic and mixed phospholipid vesicles with a binding strength that correlates with the protein net charge and the presence of clustered basic amino acid residues. PMID: 17176095

19. Notch-dependent cytoplasmic CD3 expression can only be achieved during the early phase of NK-cell differentiation. PMID: 17630354

21. Data show that Nck forms a complex with an atypical PxxDY motif of the CD3epsilon tail, which encompasses Tyr166 within the activation motif and a T-cell receptor endocytosis signal. PMID: 18555270
