Automated description from the Alliance of Genome Resources (Release 5.4.0)
Enables GTPase activator activity and small GTPase binding activity. Involved in several processes, including modification of dendritic spine; negative regulation of Rac protein signal transduction; and neurotransmitter receptor transport, endosome to postsynaptic membrane. Located in dendritic spine. Is active in glutamatergic synapse. Is expressed in central nervous system; olfactory epithelium; respiratory system; and retina. Orthologous to human ARHGAP44 (Rho GTPase activating protein 44).
