Predicted to enable small GTPase binding activity. Predicted to be involved in several processes, including Golgi ribbon formation; protein localization to ciliary membrane; and vesicle tethering to Golgi. Predicted to act upstream of or within animal organ development and protein glycosylation. Located in inner acrosomal membrane and outer acrosomal membrane. 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]
