Stability, folding dynamics, and long-range conformational transition of the synaptic t-SNARE complex [PDF]
Synaptic soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) couple their stepwise folding to fusion of synaptic vesicles with plasma membranes.

Snake and spider toxins induce a rapid recovery of function of botulinum neurotoxin paralysed neuromuscular junction [PDF]
Botulinum neurotoxins (BoNTs) and some animal neurotoxins (-Bungarotoxin, -Btx, from elapid snakes and -Latrotoxin, -Ltx, from black widow spiders) are pre-synaptic neurotoxins that paralyse motor axon terminals with similar clinical outcomes in patients.

α-SNAP Enhances SNARE Zippering by Stabilizing the SNARE Four-Helix Bundle
Intracellular membrane fusion is mediated by dynamic assembly and disassembly of soluble N-ethylmaleimide-sensitive factor (NSF) attachment protein (SNAP) receptors (SNAREs). α-SNAP guides NSF to disassemble SNARE complexes after membrane fusion.

Munc18-1 induces conformational changes of syntaxin-1 in multiple intermediates for SNARE assembly
In neuronal exocytosis, SNARE assembly into a stable four-helix bundle drives membrane fusion. Previous studies have revealed that the SM protein Munc18-1 plays a critical role for precise SNARE assembly with the help of Munc13-1, but the underlying ...

LRRK2 phosphorylates pre-synaptic N-ethylmaleimide sensitive fusion (NSF) protein enhancing its ATPase activity and SNARE complex disassembling rate [PDF]
Background Lrrk2, a gene linked to Parkinson\u2019s disease, encodes a large scaffolding protein with kinase and GTPase activities implicated in vesicle and cytoskeletal-related processes.

Analysis of SEC9 suppression reveals a relationship of SNARE function to cell physiology. [PDF]
BACKGROUND:Growth and division of Saccharomyces cerevisiae is dependent on the action of SNARE proteins that are required for membrane fusion. SNAREs are regulated, through a poorly understood mechanism, to ensure membrane fusion at the correct time and ...

A model for the self-organization of vesicular flux and protein distributions in the Golgi apparatus [PDF]
The generation of two non-identical membrane compartments via exchange of vesicles is considered to require two types of vesicles specified by distinct cytosolic coats that selectively recruit cargo and two membrane-bound SNARE pairs that specify fusion ...

An electrostatically preferred lateral orientation of SNARE complex suggests novel mechanisms for driving membrane fusion. [PDF]
Biological membrane fusion is a basic cellular process catalyzed by SNARE proteins and additional auxiliary factors. Yet, the critical mechanistic details of SNARE-catalyzed membrane fusion are poorly understood, especially during rapid synaptic ...

Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion. [PDF]
The molecular underpinnings of synaptic vesicle fusion for fast neurotransmitter release are still unclear. Here, we used a single vesicle-vesicle system with reconstituted SNARE and synaptotagmin-1 proteoliposomes to decipher the temporal sequence of ...
