TLDR
The existence of numerous SNARE-related proteins, each apparently specific for a single kind of vesicles or target membrane, indicates that NSF and SNAPs may be universal components of a vesicle fusion apparatus common to both constitutive and regulated fusion (including neurotransmitter release), in which the SNAREs may help to ensure vesICLE-to-target specificity.Abstract:
The N-ethylmaleimide-sensitive fusion protein (NSF) and the soluble NSF attachment proteins (SNAPs) appear to be essential components of the intracellular membrane fusion apparatus. An affinity purification procedure based on the natural binding of these proteins to their targets was used to isolate SNAP receptors (SNAREs) from bovine brain. Remarkably, the four principal proteins isolated were all proteins associated with the synapse, with one type located in the synaptic vesicle and another in the plasma membrane, suggesting a simple mechanism for vesicle docking. The existence of numerous SNARE-related proteins, each apparently specific for a single kind of vesicle or target membrane, indicates that NSF and SNAPs may be universal components of a vesicle fusion apparatus common to both constitutive and regulated fusion (including neurotransmitter release), in which the SNAREs may help to ensure vesicle-to-target specificity.read more

SNAREs--engines for membrane fusion.
TL;DR: A fascinating picture of these robust nanomachines is emerging, which seems to be conserved and adaptable for fusion reactions as diverse as those involved in cell growth, membrane repair, cytokinesis and synaptic transmission.

TL;DR: Recombinant v- and t- SNARE proteins reconstituted into separate lipid bilayer vesicles assemble into SNAREpins-SNARE complexes linking two membranes, leading to spontaneous fusion of the docked membranes at physiological temperature.

The synaptic vesicle cycle
TL;DR: Insight into how Munc18-1 collaborates with SNARE proteins in fusion, how the vesicular Ca2+ sensor synaptotagmin 1 triggers fast release, and how thevesicular Rab3 protein regulates release by binding to the active zone proteins RIM1 alpha and RIM2 alpha has advanced the understanding of neurotransmitter release.

Mechanisms of intracellular protein transport
TL;DR: The general protein apparatus used by all eukaryotes for intracellular transport, including secretion and endocytosis, and for triggered exocyTosis of hormones and neurotransmitters, is uncovered.

The synaptic vesicle cycle: a cascade of protein–protein interactions
TL;DR: A convergence of results now allows formulation of molecular models for key steps of the synaptic vesicle cycle, which may form the basis for a mechanistic understanding of higher neural function.
