Protein Structure
UniProt Annotation
Function GTPase activator for the Rho-type GTPases by converting them to an inactive GDP-bound state. Has a substantial GAP activity toward CDC42 and RAC1 and less toward RHOA. Has a role in regulating adhesion of hematopoietic cells to the extracellular matrix. Binds phosphoinositides, and has the highest affinity for phosphatidylinositol 3,4,5-trisphosphate, followed by phosphatidylinositol 3,4-bisphosphate and phosphatidylinositol 4,5-bisphosphate. {ECO:0000269PubMed:11396949}.
Subcellular Localization
Disease Associations
Tissue Specificity Predominantly expressed in peripheral blood leukocytes, spleen, and thymus. {ECO:0000269PubMed:11396949}.
