T-cell surface glycoprotein CD3 zeta chain, also known as CD3z, CD247, CD3-zeta, T3z, CD3H, CD3Q, TCRZ, and IMD25, is a single-pass type I transmembrane protein of the CD3Z/FCER1G family. CD3z contains a short (9 amino acid) extracellular region and 113 amino acid cytoplasmic region with 3 ITAM (immune tyrosine activation motif) domains. CD3z is part of the T-cell receptor (TCR)/CD3 complex and is involved in T-cell development and signal transduction. The TCR/CD3 complex of T-lymphocytes consists of either a TCR alpha/beta or TCR gamma/delta heterodimer co-expressed at the cell surface with the invariant subunits of CD3 labeled gamma, delta, epsilon, zeta, and eta. CD3z plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways leading to the activation of T cells. Low expression of the antigen results in impaired immune response. CD3z forms either homodimers or heterodimers with CD3-eta. CD3z is phosphorylated on its Tyr residues after T-cell receptor triggering. CD3z interacts with many signaling molecules including SHB, ZAP70, SHC1, PTPRC, SLA, SLA2, DOCK2,TRAT1, HIV-1, and HIV-2 Nef protein. this interaction induces down-regulation of cell surface TCR/CD3 complexes. Defects in the CD3g gene are a cause of immunodeficiency 25 (IMD25), an immunological deficiency characterized by T-cells impaired immune response to alloantigens, tetanus toxoid and mitogens.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) Reverse (or 3'-end) primer: 5’-CGGGAAGCAATAGCATGATA-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
