VESICLE FUSION Sensing Calcium During Membrane Fusion

The minimal machinery required for calcium-stimulated fusion, such as occurs during regulated secretion or neurotransmitter release, has been the subject of much controversy. Using a reconstituted system, Tucker et al. now show a robust requirement for the cytoplasmic tail of the synaptic vesicle protein synaptotagmin to act as a calcium sensor during SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor)-mediated fusion in reconstituted liposomes.
