Predicted to enable GTP binding activity and GTPase activity. Involved in response to lithium ion. Predicted to be located in axoneme. Predicted to be active in ciliary membrane; motile cilium; and non-motile cilium. Human ortholog(s) of this gene implicated in Joubert syndrome 8. Orthologous to human ARL13B (ADP ribosylation factor like GTPase 13B). [provided by Alliance of Genome Resources, Apr 2022]
