Target

  • Function
    Functions as a RAC1 guanine nucleotide exchange factor (GEF), activating Rac proteins by exchanging bound GDP for free GTP. Its activity is synergistically activated by phosphatidylinositol-3,4,5-triphosphate and the beta gamma subunits of heterotrimeric G protein. Mediates the activation of RAC1 in a PI3K-dependent manner. May be an important mediator of Rac signaling, acting directly downstream of both G protein-coupled receptors and phosphoinositide 3-kinase.
  • Tissue specificity
    Isoform 1 is highly expressed in skeletal muscle, heart and placenta, absent from peripheral blood leukocytes. Isoform 2 is expressed in skeletal muscle, kidney, small intestine, and placenta. Isoform 3 is expressed in the heart.
  • Sequence similarities
    Contains 2 DEP domains.
    Contains 1 DH (DBL-homology) domain.
    Contains 2 PDZ (DHR) domains.
    Contains 1 PH domain.
  • Domain
    PH domain confers substrate specificity and recognition. Able to discriminate between RAC1, RHOA, and CDC42.
    DH domain alone was unable to confer substrate specificity and recognition.
