Enables GTP binding activity and GTPase activity. Involved in several processes, including neurotransmitter receptor transport, endosome to postsynaptic membrane; positive regulation of protein localization to plasma membrane; and regulation of long-term neuronal synaptic plasticity. Located in postsynaptic recycling endosome and transport vesicle. Is active in Schaffer collateral - CA1 synapse and glutamatergic synapse. Orthologous to human RAB11A (RAB11A, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
