Predicted to enable GTPase activity. Predicted to be involved in intracellular protein transport and lipid droplet organization. Predicted to be active in Golgi apparatus. Human ortholog(s) of this gene implicated in Warburg micro syndrome 3. Orthologous to human RAB18 (RAB18, member RAS oncogene family).
WB Description
rab-18 encodes a small GTPase homologous to the Rab GTPases that function in endocytosis, membrane fusion, and vesicular trafficking events; the precise biological role and expression pattern of rab-18 are not yet known.
