Can Ca2+ be released from secretory granules or synaptic vesicles?
Recent studies on single isolated secretory granules, as well as secretory granules in intact cells, show that Ca2+ is released from the granule store into the cytosol via a messenger-mediated pathway following agonist binding. This is important for generation of localized cytosolic Ca2+ signals which can initiate exocytosis.
