Mass spectrometry uncovers intermediates and off-pathway complexes for SNARE complex assembly
Chemical cross-linking and native mass spectrometry aid the thorough investigation of complex formation and multimerisation of synaptic vesicle fusion-mediating SNARE complex, including the role of complexin-1 in its assembly.

In vitro fusion of single synaptic and dense core vesicles reproduces key physiological properties.
Regulated exocytosis of synaptic vesicles is substantially faster than of endocrine dense core vesicles despite similar molecular machineries. The reasons for this difference are unknown and could be due to different regulatory proteins, different ...

The SNARE Protein Syntaxin 3 Confers Specificity for Polarized Axonal Trafficking in Neurons. [PDF]
Cell polarity and precise subcellular protein localization are pivotal to neuronal function. The SNARE machinery underlies intracellular membrane fusion events, but its role in neuronal polarity and selective protein targeting remain unclear.

The fate of synaptic vesicle components upon fusion
Neurotransmitter release relies on the fusion of synaptic vesicles with the plasma membrane of synaptic boutons, which is followed by the recycling of vesicle components and formation of new vesicles. It is not yet clear whether upon fusion the vesicles persist as multimolecular patches in the plasma membrane, or whether they segregate into individual ...

Calcium-Independent Exo-endocytosis Coupling at Small Central Synapses
Summary: At presynaptic terminals, neurotransmitters are released by synaptic vesicle exocytosis at the active zone. In order to maintain efficient neurotransmission and proper synaptic structure, sites of vesicle fusion must be cleared rapidly by ...

α-Synuclein-induced deformation of small unilamellar vesicles
α-Synuclein is a small neuronal protein that reversibly associates with lipid membranes. The membrane interactions are believed to be central to the healthy function of this protein involved in synaptic plasticity and neurotransmitter release.

Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

α-Synuclein is a presynaptic protein that is implicated in Parkinson's and other neurodegenerative diseases. Physiologically, native α-synuclein promotes presynaptic SNARE-complex assembly, but its molecular mechanism of action remains unknown.
