title: Fusion has found its calcium sensor.
abstract: Synaptic vesicle exocytosis, a finely tuned process that results in rapid neurotransmitter release, is still not fully understood. Studies in a simple reconstituted lipid bilayer system have now definitively demonstrated that synaptotagmin has a key role in calcium-mediated exocytosis and have also revealed additional aspects of exocytic fusion.
