Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 70 kDa (predicted molecular weight: 70 kDa).


  • FunctionPlays a role in T-cell development and lymphocyte activation. Essential for TCR-mediated IL-2 production. Isoform 1 induces TCR-mediated signal transduction, isoform 2 does not.
  • Tissue specificityExpressed in T- and natural killer cells.
  • Involvement in diseaseDefects in ZAP70 are the cause of selective T-cell defect (STD) [MIM:176947]. STD is an autosomal recessive form of severe combined immunodeficiency characterized by a selective absence of CD8-type T-cells.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. SYK/ZAP-70 subfamily.
    Contains 1 protein kinase domain.
    Contains 2 SH2 domains.
  • DomainThe SH2 domains bind to the phosphorylated tyrosine-based activation motif (TAM) of CD3Z and the non-canonical phosphorylated tyrosine-based activation motif (TAM) of RHOH.
  • Post-translational
    Phosphorylated on tyrosine residues upon T-cell antigen receptor (TCR) stimulation. Tyr-319 phosphorylation is essential for full activity.
  • Cellular localizationCytoplasm. Cell membrane. After antigen stimulation, isoform 1 concentrates at the immunological synapse and isoform 2 remains cytoplasmic. Co-localizes together with RHOH in the immunological synapse. RHOH is required for its proper localization to the cell membrane and cytoskeleton fractions in the thymocytes.
