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

    • Function

      Phosphatidylinositol 3,4,5-trisphosphate-dependent guanine nucleotide exchange factor (GEF) which plays a role in the activation of Rho GTPases RAC1, RhoA and CDC42. Can regulate cell morphology in cooperation with activated RAC1. Plays a role in Th2 (T helper cells) development and/or activation, perhaps by interfering with ZAP-70 signaling.
    • Tissue specificity

      Broadly expressed in the immune system and can be detected in T and B-cells.
    • Sequence similarities

      Contains 1 PH domain.
    • Domain

      The PH domain is essential for phosphatidylinositol 3,4,5-trisphosphate binding.
    • Post-translational

      Tyrosine-phosphorylated by tyrosine-protein kinase LCK in response to T-cell activation.
    • Cellular localization

      Cytoplasm. Cell membrane. Nucleus. Recruited to the plasma membrane upon binding phosphatidylinositol 3,4,5-trisphosphate.
