Witryna25 maj 2007 · The Ca2+ sensor required for fast fusion is synaptotagmin-1. The acti … Synaptic vesicles loaded with neurotransmitters are exocytosed in a soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE)-dependent manner after presynaptic depolarization induces calcium ion (Ca2+) influx. The Ca2+ … WitrynaSynaptosomal-Associated Protein, 25kDa (SNAP-25) is a Target Soluble NSF (N-ethylmaleimide-sensitive factor) Attachment Protein Receptor protein encoded by the SNAP25 gene found on chromosome 20p12.2 in humans. SNAP-25 is a component of the trans-SNARE complex, which accounts for membrane fusion specificity and …

WitrynaThe Ca(2+)-triggered exocytotic process is regulated by synaptotagmin (Syt), a vesicular Ca(2+)-binding C2 domain protein. Synaptotagmin 1 (Syt1), the most studied major isoform among 16 Syt isoforms, mediates Ca(2+)-triggered synaptic vesicle exocytosis by interacting with the target membranes and SNARE/complexin complex. Witryna14 wrz 2012 · Synaptotagmin-1, a protein associated with the vesicular membrane, is considered as a Ca 2+ sensor for neurotransmitter ... Arakawa, T.; Tajima, Y.
