  • Application notesIs unsuitable for IP.
  • Target

    • FunctionActs as an adapter protein of the FYN and LCP2 signaling cascades in T cells. Modulates the expression of interleukin-2 (IL-2). Involved in platelet activation. Prevents the degradation of SKAP1 and SKAP2.
    • Tissue specificityExpressed in hematopoietic tissues such as myeloid and T-cells, spleen and thymus. Not expressed in B-cells, nor in non-lymphoid tissues.
    • Sequence similaritiesContains 1 SH3 domain.
    • Post-translational
      T-cell receptor ligation leads to increased tyrosine phosphorylation.
    • Cellular localizationCytoplasm. Nucleus.
