Predicted to be involved in cilium assembly. Predicted to act upstream of or within cell projection organization. Predicted to be located in cell projection; membrane; and vacuole. Predicted to be integral component of membrane. Predicted to be active in cilium. Is expressed in several structures, including 4th ventricle choroid plexus; brain ventricular layer; choroid invagination; genitourinary system; and gut gland. Human ortholog(s) of this gene implicated in Joubert syndrome 16. Orthologous to human TMEM138 (transmembrane protein 138). [provided by Alliance of Genome Resources, Apr 2022]
