Calcium-dependent secretion activator 1 is a protein that in humans is encoded by the CADPS gene.CADPS encodes a novel neural/endocrine-specific cytosolic and peripheral membrane protein required for the Ca2+-regulated exocytosis of secretory vesicles. CADPS acts at a stage in exocytosis that follows ATP-dependent priming which involves the essential synthesis of phosphatidylinositol 45-bisphosphate (PtdIns(45)P2).
