Lysophosphatidylcholine inhibits membrane‐associated SNARE complex disassembly [PDF]
AbstractIn cells, N‐ethylmaleimide‐sensitive factor (NSF) attachment protein receptors called SNAREs are involved in membrane fusion. In neurons, for example, target membrane proteins SNAP‐25 and syntaxin called t‐SNAREs present at the pre‐synaptic membrane, and a synaptic vesicle‐associated membrane protein (VAMP) or v‐SNARE, is part of the conserved ...

The role of the N-D1 linker of the N-ethylmaleimide-sensitive factor in the SNARE disassembly. [PDF]
N-ethylmaleimide-sensitive factor (NSF) is a member of the type II AAA+ (ATPase associated with various cellular activities) family. It plays a critical role in intracellular membrane trafficking by disassembling soluble NSF attachment protein receptor ...

Molecular Dynamics Simulations of the Proteins Regulating Synaptic Vesicle Fusion
Neuronal transmitters are packaged in synaptic vesicles (SVs) and released by the fusion of SVs with the presynaptic membrane (PM). An inflow of Ca2+ into the nerve terminal triggers fusion, and the SV-associated protein Synaptotagmin 1 (Syt1) serves as ...

Epigallocatechin gallate inhibits SNARE‐dependent membrane fusion by blocking trans‐SNARE assembly
Insulin secretion is a signal‐triggered process that requires membrane fusion between the secretory granules and plasma membrane in pancreatic β cells. The exocytosis of insulin is mediated by target‐soluble N‐ethylmaleimide sensitive factor attachment ...

Sec17p and HOPS, in distinct SNARE complexes, mediate SNARE complex disruption or assembly for fusion [PDF]
SNARE functions during membrane docking and fusion are regulated by Sec1/Munc18 (SM) chaperones and Rab/Ypt GTPase effectors. These functions for yeast vacuole fusion are combined in the six-subunit HOPS complex. HOPS facilitates Ypt7p nucleotide exchange, is a Ypt7p effector, and contains an SM protein.

Summary: The AAA+ NSF complex is responsible for SNARE complex disassembly both before and after membrane fusion. Loss of NSF function results in pronounced developmental and degenerative defects. In a genetic screen for sensory deficits in zebrafish, we

The COG complex interacts with multiple Golgi SNAREs and enhances fusogenic SNARE complexes assembly [PDF]
Multisubunit tethering complexes (MTCs) positively regulate vesicular fusion by as yet unclear mechanism. In this study we provide evidence that the MTC COG enhances the assembly of fusogenic Golgi SNARE complexes and concomitantly prevents nonfusogenic tSNARE interactions.

VAMP721 conformations unmask an extended motif for K+ channel binding and gating control [PDF]
Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins play a major role in membrane fusion and contribute to cell expansion, signaling, and polar growth in plants.

COG complexes form spatial landmarks for distinct SNARE complexes [PDF]
Vesicular tethers and SNAREs (soluble N-ethylmalemide-sensitive fusion attachment protein receptors) are two key protein components of the intracellular membrane-trafficking machinery. The conserved oligomeric Golgi (COG) complex has been implicated in the tethering of retrograde intra-Golgi vesicles.
