eLife, 2022 Synaptic communication relies on the fusion of synaptic vesicles with the plasma membrane, which leads to neurotransmitter release. This exocytosis is triggered by brief and local elevations of intracellular Ca2+ with remarkably high sensitivity.

A mouse model of autism implicates endosome pH in the regulation of presynaptic calcium entry. [PDF]
, 2018 Psychoactive compounds such as chloroquine and amphetamine act by dissipating the pH gradient across intracellular membranes, but the physiological mechanisms that normally regulate organelle pH remain poorly understood.

The SNARE Protein Syntaxin 3 Confers Specificity for Polarized Axonal Trafficking in Neurons. [PDF]
, 2016 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.

Identification of a synaptic vesicle-specific membrane protein with a wide distribution in neuronal and neurosecretory tissue. [PDF]
, 1981 Two different monoclonal antibodies, characterized initially as binding synaptic terminal regions of rat brain, bind a 65,000-dalton protein, which is exposed on the outer surface of brain synaptic vesicles. Immunocytochemical experiments at the electron

Molecular correlates of synaptic vesicle docking and fusion
Current Opinion in Neurobiology, 1994 The mechanisms responsible for neurotransmitter release at the synapse have been extensively studied using biochemical, genetic, and cell biological approaches. Several significant advances have recently contributed towards an improved understanding of the molecular details of both synaptic vesicle docking and fusion, and of the general process of ...

Mass spectrometry uncovers intermediates and off-pathway complexes for SNARE complex assembly
Communications Biology, 2023 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.

Long Term Potentiation (LTP) and Long Term Depression (LTD) Cause Differential Spatial Redistribution of the Synaptic Vesicle Protein Synaptophysin in the Middle Molecular Layer of the Dentate Gyrus in Rat Hippocampus [PDF]
, 2016 The presynaptic modifications that accompany long-term changes in synaptic plasticity are still not fully understood. Synaptophysin is a major synaptic vesicle protein involved in neurotransmitter release. We have used quantitative electron microscopy to

Beyond the MUN domain, Munc13 controls priming and depriming of synaptic vesicles
Cell ReportsSummary: Synaptic vesicle docking and priming are dynamic processes. At the molecular level, SNAREs (soluble NSF attachment protein receptors), synaptotagmins, and other factors are critical for Ca2+-triggered vesicle exocytosis, while disassembly ...

In vitro fusion of single synaptic and dense core vesicles reproduces key physiological properties.
, 2019 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 ...
