  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function
      Positively regulates T-cell receptor signaling by enhancing the MAP kinase pathway. Required for optimal conjugation between T-cells and antigen-presenting cells by promoting the clustering of integrin ITGAL on the surface of T-cells. May be involved in high affinity immunoglobulin epsilon receptor signaling in mast cells.
    • Tissue specificity
      Highly expressed in thymocytes and peripheral blood lymphocytes. Also expressed in spleen cells and testis. Present in T-cells (at protein level).
    • Sequence similarities
      Belongs to the SKAP family.
      Contains 1 PH domain.
      Contains 1 SH3 domain.
    • Domain
      The SH3 domain interacts with FYB.
    • Post-translational
      Phosphorylated on tyrosines. Phosphorylation by FYN on Tyr-271 is required for GRB2 interaction. Phosphorylation by FYN on Tyr-295 abolishes interaction with FYB. Tyr-232 is dephosphorylated by PTPRC.
    • Cellular localization
      Cytoplasm. Nucleus. Cell membrane. Upon T-cell stimulation, translocates to lipid rafts at the cell membrane.
