  • Function
    Required for TCR (T-cell antigen receptor)- and pre-TCR-mediated signaling, both in mature T-cells and during their development. Involved in FCGR3 (low affinity immunoglobulin gamma Fc region receptor III)-mediated signaling in natural killer cells and FCER1 (high affinity immunoglobulin epsilon receptor)-mediated signaling in mast cells. Couples activation of these receptors and their associated kinases with distal intracellular events such as mobilization of intracellular calcium stores, PKC activation, MAPK activation or cytoskeletal reorganization through the recruitment of PLCG1, GRB2, GRAP2, and other signaling molecules.
  • Tissue specificity
    Expressed in thymus, T-cells, NK cells, mast cells and, at lower levels, in spleen. Present in T-cells but not B-cells (at protein level).
  • Post-translational
    Phosphorylated on tyrosines by ZAP-70 upon TCR activation, or by SYK upon other immunoreceptor activation; which leads to the recruitment of multiple signaling molecules. Is one of the most prominently tyrosine-phosphorylated proteins detected following TCR engagement. May be dephosphorylated by PTPRJ.
    Palmitoylation of Cys-26 and Cys-29 is required for raft targeting and efficient phosphorylation.
  • Cellular localization
    Cell membrane. Present in lipid rafts.

  • Antibody recognizes approximately 36 KD size protein and its degradation products in mouse normal tissues. However, antibody specifically reacts with a approximately 46 KD protein in human tumor cell lines Jurkatt and K562. This immunoreactive 46 KD protein appears to be more stable than 36 KD immunoreactive protein observed in normal mouse tissue. (Lane 1, Human T cell line Jurkatt. Lane 2, Mouse Lung Lane 3, Human cell line K562 Lane 4, Mouse Heart).
