Predicted to enable GTPase activity and calcium-dependent protein binding activity. Predicted to be involved in several processes, including Wnt signaling pathway; cell projection assembly; and positive regulation of cell adhesion. Predicted to act upstream of or within several processes, including GABAergic synaptic transmission; neuron development; and regulation of neuron maturation. Located in cytoskeleton; cytosol; and growth cone. Orthologous to human RAC3 (Rac family small GTPase 3). [provided by Alliance of Genome Resources, Apr 2022]
