The Rab GTPase effector Noc2 was brought into the limelight by a recent publication that demonstrated its requirements at different stages of regulated exocytosis. Noc2 knockout resulted in distinct abnormalities in endocrine and exocrine cells, ranging from the accumulation of secretory granules of increased size to impairments in the regulated release of their secretory products. Explanations for these defects are beginning to emerge and they promise to reveal some of the most jealously kept secrets of regulated exocytosis.
