Synaptic vesicle protein
WebSep 25, 2016 · Biochemists have isolated many of the key proteins of SVs. These proteins fall into two major classes: transport proteins involved in neurotransmitter uptake and trafficking proteins that participate in synaptic vesicle exocytosis, endocytosis, and recycling (several mentioned in Fig. 1) [].Among these proteins are those in the synaptic … WebThese results suggest, therefore, that osthole or imperatorin-mediated facilitation of glutamate release involves modulation of downstream events controlling synaptic vesicle recruitment and exocytosis, possibly through an increase of CaMKII activation and synapsin I phosphorylation, thereby increasing synaptic vesicle availability for exocytosis.

In the central nervous system (CNS), cell-to-cell communication is crucial to ensure proper development and maintenance of homeostatic conditions [1,2].Extracellular vesicles (EVs) are membrane-bound carriers packed with proteins, metabolites, and nucleic acids (including DNA, mRNA, and microRNAs), …
WebBotulinum neurotoxins (BoNT/A-G) act by blocking synaptic vesicle exocytosis. Whether BoNTs disrupt additional neuronal functions has not been addressed. Here we report that cleavage of syntaxin 1 by BoNT/C, and cleavage of SNAP-25 by BoNT/E both induce degeneration of neurons. WebSynapses are the site of chemical communication between neurons and between neurons and muscles. The synaptic vesicle (SV) is a prominent presynaptic organelle which contains chemical neurotransmitters and fuses with the plasma membrane to mediate neurotransmission. There are about 50 or so synaptic proteins which are either integral …
