Predicted to enable several functions, including GTP binding activity; GTPase activity; and calcium-dependent protein binding activity. Acts upstream of or within several processes, including GABAergic synaptic transmission; neuron development; and regulation of neuron maturation. Predicted to be located in several cellular components, including growth cone; neuronal cell body; and perinuclear region of cytoplasm. Predicted to be part of filamentous actin. Predicted to be active in several cellular components, including cell cortex; cytoplasmic vesicle; and neuron projection. Is expressed in brain and genitourinary system. Orthologous to human RAC3 (Rac family small GTPase 3). [provided by Alliance of Genome Resources, Apr 2022]
