Predicted to enable GDP binding activity; GTP binding activity; and GTPase activity. Involved in positive regulation of dendrite morphogenesis. Located in neuron projection. Is expressed in several structures, including cranial ganglion; jaw bone; medulla oblongata basal plate mantle layer; neural retina; and thymus primordium. Orthologous to human RAB21 (RAB21, member RAS oncogene family).
