Predicted to enable GTPase activity; guanyl ribonucleotide binding activity; and microtubule binding activity. Involved in cilium assembly. Predicted to be located in several cellular components, including microtubule cytoskeleton; midbody; and photoreceptor connecting cilium. Predicted to be active in cytoplasm and microtubule cytoskeleton. Is expressed in eye; kidney; and oocyte. Human ortholog(s) of this gene implicated in Joubert syndrome and retinitis pigmentosa 83. Orthologous to human ARL3 (ARF like GTPase 3).
