Predicted to enable GTPase activity. Predicted to be involved in several processes, including cellular defense response; negative regulation of protein import into nucleus; and organelle assembly. Predicted to act upstream of or within several processes, including embryonic morphogenesis; regulation of smoothened signaling pathway; and spinal cord dorsal/ventral patterning. Predicted to be located in several cellular components, including centrosome; cytosol; and phagocytic vesicle. Predicted to be active in autophagosome and endosome membrane. Human ortholog(s) of this gene implicated in Carpenter syndrome. Orthologous to human RAB23 (RAB23, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
