Predicted to enable GTPase activator activity. Predicted to be involved in postsynapse organization. Predicted to be located in cytoskeleton and nucleus. Predicted to be active in cytoplasm and glutamatergic synapse. Is expressed in several structures, including central nervous system; ganglia; gut; nose; and skeletal musculature. Orthologous to human ARHGAP39 (Rho GTPase activating protein 39). [provided by Alliance of Genome Resources, Apr 2022]
