Predicted to enable GTPase activator activity and growth factor activity. Predicted to be involved in regulation of cilium assembly. Predicted to be located in centrosome; ciliary basal body; and cytosol. Predicted to be active in intracellular membrane-bounded organelle. Orthologous to human RABEP2 (rabaptin, RAB GTPase binding effector protein 2). [provided by Alliance of Genome Resources, Apr 2022]
