Structural insights into the molecular mechanism of Ca(2+)-dependent exocytosis

Curr Opin Neurobiol. 2000 Jun;10(3):293-302. doi: 10.1016/s0959-4388(00)00098-2.


The fusion of vesicles with target membranes is controlled by a complex network of protein-protein and protein-lipid interactions. Recent structures of the SNARE complex, synaptotagmin III, nSec1, domains of NSF and its adaptor SNAP, along with Rab3 and some of its effectors, provide the framework for developing molecular models of vesicle fusion and for designing experiments to test these models. Ultimately, this knowledge of the structures of higher-order complexes and their dynamic behavior will allow us to obtain a full understanding of the vesicle fusion protein machinery.
