Predicted to enable GTPase activator activity. Predicted to be involved in regulation of Rac protein signal transduction and regulation of actin cytoskeleton organization. Predicted to act upstream of or within actin filament organization and calcium-ion regulated exocytosis. Located in plasma membrane. Is expressed in limb and limb mesenchyme. Orthologous to human ARHGAP17 (Rho GTPase activating protein 17). [provided by Alliance of Genome Resources, Apr 2022]
