Functional cooperation of α-synuclein and VAMP2 in synaptic vesicle recycling
Proceedings of the National Academy of Sciences of the United States of America, 2019 The function of α-synuclein (α-syn) has been long debated, and two seemingly divergent views have emerged. In one, α-syn binds to VAMP2, acting as a SNARE chaperone—but with no effect on neurotransmission—while another posits that α-syn attenuates ...

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

Vesicle Clustering in a Living Synapse Depends on a Synapsin Region that Mediates Phase Separation
Cell Reports, 2020 Summary: Liquid-liquid phase separation is an increasingly recognized mechanism for compartmentalization in cells. Recent in vitro studies suggest that this organizational principle may apply to synaptic vesicle clusters. Here we test this possibility by

Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion. [PDF]
, 2012 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 ...

Research progress on vesicle cycle and neurological disorders
Journal of Pharmacy & Pharmaceutical Sciences, 2021 Neurons are special polarized cells whose synaptic vesicles release neurotransmitters into the synaptic cleft, acting on postsynaptic receptors and thus transmitting information from presynaptic to postsynaptic states.

Carbonic anhydrase inhibitor acetazolamide shifts synaptic vesicle recycling to a fast mode at the mouse neuromuscular junction [PDF]
, 2017 Acetazolamide (AZ), a molecule frequently used to treat different neurological syndromes, is an inhibitor of the carbonic anhydrase (CA), an enzyme that regulates pH inside and outside cells.

C-terminal calcium binding of α-synuclein modulates synaptic vesicle interaction
Nature Communications, 2018 Alpha-synuclein is known to bind to small unilamellar vesicles (SUVs) via its N terminus, which forms an amphipathic alpha-helix upon membrane interaction.
