Predicted to enable small GTPase binding activity. Involved in protein localization to ciliary membrane. Acts upstream of or within Golgi organization; animal organ development; and protein glycosylation. Located in acrosomal membrane and cis-Golgi network. Used to study achondrogenesis type IA. Human ortholog(s) of this gene implicated in achondrogenesis type IA. Orthologous to human TRIP11 (thyroid hormone receptor interactor 11). [provided by Alliance of Genome Resources, Apr 2022]
