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.
Predicted to enable GTPase activity. Predicted to be involved in intracellular protein transport and lipid droplet organization. Predicted to be located in Golgi apparatus. Human ortholog(s) of this gene implicated in Warburg micro syndrome 3. Is an ortholog of human RAB18 (RAB18, member RAS oncogene family).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
