Polyclonal Rabbit Affinity Purified B
Neurotransmitter release is mediated by exocytosis of synaptic vesicles at the presynaptic active zone of nerve terminals (1). Synaptic vesicles undergo a trafficking cycle to support rapid and repeated cycles of neurotransmitter release. Calcium-triggered exocytosis is the focal point of the vesicle cycle, which is followed by different routes of endocytosis and recycling. Recycling then leads to the docking and priming of the vesicles for another round of exocytocis and endocytosis. The synaptotagmins are integral membrane proteins of synaptic vesicles. Synaptotagmins may serve as the calcium sensors that trigger neuortransmitter release (2,3). More than 13 synaptotagmins have been described, and synaptotagmin I is among the best characterized isoforms. Synaptotagmin I is an abundant constituent of synaptic vesicles that binds calcium ions through two C2 domains. It is thought that synaptotagmin I triggers exocytosis in a calcium dependent manner, and may also play a key role in endocytosis following membrane fusion. Synaptotagmin is phosphorylated by multiple protein kinases, and these phosphorylation events may play a regulatatory role in both exocytotic and endocytotic events.
