Predicted to enable GTPase activator activity. Predicted to be involved in small GTPase mediated signal transduction. Predicted to act upstream of or within Rho protein signal transduction. Located in actin cytoskeleton; cell cortex; and postsynaptic density. Is expressed in several structures, including brain; genitourinary system; liver; lung; and spleen. Used to study autism spectrum disorder. Orthologous to human ARHGAP32 (Rho GTPase activating protein 32). [provided by Alliance of Genome Resources, Apr 2022]
