Application Abreviews Notes
WB 1/500 - 1/2000. Detects a band of approximately 21 kDa (predicted molecular weight: 19 kDa).
IP 1/50.
ICC 1/250 - 1/500.
  • Application notesIs unsuitable for Flow Cyt or IHC-P.
  • Target

    • FunctionProbable role in assembly and expression of the TCR complex as well as signal transduction upon antigen triggering.
    • Involvement in diseaseDefects in CD247 are the cause of immunodeficiency due to defect in CD3-zeta (CD3ZID) [MIM:610163]. An immunological deficiency characterized by T-cells impaired immune response to alloantigens, tetanus toxoid and mitogens.
    • Sequence similaritiesBelongs to the CD3Z/FCER1G family.
      Contains 3 ITAM domains.
    • DomainThe ITAM domains mediate interaction with SHB.
    • Post-translational
      Phosphorylated on Tyr residues after T-cell receptor triggering.
    • Cellular localizationMembrane.
