Arhgap44 - Rho GTPase activating protein 44

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). [provided by Alliance of Genome Resources, Apr 2022]
