Target Species

Human

Target Name

ARHGAP24

Target Full Name

Rho GTPase-activating protein 24

Target Function

Rho GTPase-activating protein involved in cell polarity, cell morphology and cytoskeletal organization. Acts as a GTPase activator for the Rac-type GTPase by converting it to an inactive GDP-bound state. Controls actin remodeling by inactivating Rac downstream of Rho leading to suppress leading edge protrusion and promotes cell retraction to achieve cellular polarity. Able to suppress RAC1 and CDC42 activity in vitro. Overexpression induces cell rounding with partial or complete disruption of actin stress fibers and formation of membrane ruffles, lamellipodia, and filopodia. Isoform 2 is a vascular cell-specific GAP involved in modulation of angiogenesis.

Target Subcellular Location

Cytoplasm, cytoskeleton. Cell junction, adherens junction. Cell junction, focal adhesion. Cell projection. Note=Localizes to actin stress fibers. In migrating cells, localizes to membrane lamellae and protusions.

Target Tissue Specificity

Isoform 1 is widely expressed with a higher level in kidney. Isoform 2 is mainly expressed in endothelial cells.
