Several Rab proteins control secretory granule trafficking and, hence, hormone release, by regulating the activity of different components of the secretory granule transport machinery. Particularly, Rab18 inhibits secretory granule movement, which leads to reduced neuropeptide and hormone secretion in PC12 pheochromocytoma cells and ACTH-secreting ATt20 cells, respectively, but how this GTPase accomplishes its role and the identity of the proteins that regulate Rab18 activity ...
