神经元具有在动作电位之后立即向突触释放一批神经递质的非凡能力。这一签名事件是可能的,同时融合的突触囊泡的数量质膜后,Ca 2+进入活性区。细胞和体外研究的结果表明,可溶性N-乙基马来酰亚胺敏感因子附着蛋白受体(SNARE)和突触结合蛋白1(Syt 1)构成了神经元中最小的快速胞吐机制。Syt 1是主要的Ca 2 +-传感器,并协调各个囊泡融合事件的同步开始,而SNARE是决定每个单个融合事件动力学的膜融合机制。这些数据还表明,Ca 2+结合的Syt 1参与了上游对接步骤,这导致融合事件的数量或释放的大小增加,留下SNARE复合物单独进行膜融合。
Neurons have the remarkable ability to release a batch of neurotransmitters into the synapse immediately after an action potential. This signature event is made possible by the simultaneous fusion of a number of synaptic vesicles to the plasma membrane upon Ca2+ entry into the active zone. The outcomes of both cellular and in vitro studies suggest that soluble N-ethylmaleimide-sensitive-factor attachment protein receptors (SNAREs) and synaptotagmin 1 (Syt1) constitute the minimal fast exocytosis machinery in the neuron. Syt1 is the major Ca2+-sensor and orchestrates the synchronous start of individual vesicle fusion events while SNAREs are the membrane fusion machinery that dictates the kinetics of each single fusion event. The data also suggest that Ca2+-bound Syt1 is involved in the upstream docking step which leads to an increase in the number of fusion events or the size of the release, leaving the SNARE complex alone to carry out membrane fusion by themselves.
