Predicted to be involved in exocytosis and positive regulation of exocytosis. Predicted to act upstream of or within dense core granule exocytosis; protein transport; and synaptic vesicle exocytosis. Predicted to be located in cytoplasmic vesicle membrane. Predicted to be active in glutamatergic synapse. Is expressed in olfactory placode and peripheral olfactory organ. Orthologous to human CADPS (calcium dependent secretion activator).
