  • Function

    Regulates the GDP/GTP exchange reaction of the Rho proteins by inhibiting the dissociation of GDP from them, and the subsequent binding of GTP to them (PubMed:8356058, PubMed:7512369). Regulates reorganization of the actin cytoskeleton mediated by Rho family members (PubMed:8262133).
  • Tissue specificity

    Detected in bone marrow, thymus and spleen.
  • Sequence similarities

    Belongs to the Rho GDI family.
  • Cellular localization

    Cytoplasm, cytosol.

    Lysates prepared using NETN lysis buffer.

  • D4 GDI was immunoprecipitated from Jurkat (human T cell leukemia cell line from peripheral blood) whole cell lysate (prepared using NETN lysis buffer; 1 mg for IP, 20% of IP loaded) with ab226350 at 6 µg/mg lysate. Western blot was performed from the immunoprecipitate using ab226350 at 0.4 µg/ml.
