Image

  • IHC image of CSB-PA10484A0Rb diluted at 1:80 and staining in paraffin-embedded human appendix tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Target Background

Function
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.

  1. The ionic CD3-epsilon -Lck interaction controls the phosphorylation level of the T-cell receptor. PMID: 28659468
  2. A novel pathogenic frameshift variant of CD3E gene has been found in two unrelated T-B+ NK+ severe combined immunodeficiency infants from Turkey. PMID: 28597365
  3. the stalk domains of NKp30 and NKp46, another NCR employing CD3zeta for signaling, were not exchangeable without drastic deficiencies in folding, plasma membrane targeting, and/or ligand-induced receptor signaling. PMID: 27754869
  4. The inducible recruitment of WASp to the TCR-CD3 complex is partially dependent of tyrosine phosphorylation of Cd3e. PMID: 26342115

  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
  7. that Nck recruitment to the TCR is fundamental to mount an efficient T cell response in vivo, and that the Nck-CD3epsilon interaction may represent a target for pharmacological modulation of the immune response. PMID: 24470497

  11. analysis of the transgenic integration site in immunodeficient tgepsilon26 human CD3epsilon transgenic mice PMID: 21203507
  12. Results suggest that generation of CD3varepsilon chain isoforms with different N-terminal sequence and pI is a general phenomenon. PMID: 19616027
  13. Recruitment of Nck by CD3 epsilon reveals a ligand-induced conformational change essential for T cell receptor signaling and synapse formation. PMID: 12110186

  15. SCID is caused by a CD3E deficiency. PMID: 15546002
  16. CD3 expression was strong in normal proximal and distal tubular epithelium and in renal oncocytomas, weak in chromophobe carcinoma, and negative in clear cell carcinomas, in papillary renal cell carcinoma, and in a transitional cell carcinoma. PMID: 16308105
  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
  18. CD3epsilon-mediated signal transduction pathway is essential for this transformation process PMID: 17507663
  19. Notch-dependent cytoplasmic CD3 expression can only be achieved during the early phase of NK-cell differentiation. PMID: 17630354
  20. In lung adenocarcinoma patients, significant decreases of MFI values for CD3epsilon, but not CD3zeta, were found in CD4+T and CD8+T cells from pleural effusion compared to peripheral blood and in peripheral blood of patients compared to healthy donors. PMID: 17668204
  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
  22. Data show that anti-CD3 monoclonal antibody (MAb)-mediated chimpanzee T-cell activation is a function of the anti-CD3 MAb isotype and is not governed by Siglec expression. PMID: 18667496
  23. Results revealed that the human CD3 epsilon subunit forms a homodimer structure, which provide insight into our understanding of the molecular assembly of the CD3 molecular complex. PMID: 19724882
