Brain contains two forms of synaptic vesicle protein 2.
Molecular cloning of a cDNA encoding synaptic vesicle protein 2 (SV2) revealed that it is homologous to a family of proton cotransporters from bacteria and fungi and to a related family of glucose transporters found in mammals. The similarity to proton cotransporters raised the possibility that SV2 might mediate the uptake of neurotransmitters into vesicles, an activity known to require a proto...
متن کاملSynaptic Vesicle Protein 2 ( SV 2 ) does not hydrolyze ATP
Synaptic vesicle protein 2 (SV2) is a transporter-like protein specifically expressed in endocrine cells and neurons, where it is localized to vesicles that undergo regulated secretion and plays an essential role in regulating neurotransmitter release. SV2 binds adenine nucleotides including ATP. Analysis of ATP transport revealed that SV2 is not an ATP transporter, nor does it affect ATP trans...

متن کاملSynaptic vesicle protein 2 enhances release probability at quiescent synapses.
We report a thorough analysis of neurotransmission in cultured hippocampal neurons lacking synaptic vesicle protein 2 (SV2), a membrane glycoprotein present in all vesicles that undergo regulated secretion. We found that SV2 selectively enhances low-frequency neurotransmission by priming morphologically docked vesicles. Loss of SV2 reduced initial release probability during a train of action po...
متن کاملPost-transcriptional regulation of synaptic vesicle protein expression and the developmental control of synaptic vesicle formation.
The regulated expression of synaptic vesicle (SV) proteins during development and the assembly of these proteins into functional SVs are critical aspects of nervous system maturation. We have examined the expression patterns of four SV proteins in embryonic hippocampal neurons developing in culture and have found that increases in the levels of these proteins result primarily from post-transcri...
