神经递质释放机制的核心由SNARE复合物和Munc 18 -1形成,SNARE复合物将囊泡和质膜结合在一起,是融合的关键,Munc 18 -1控制SNARE复合物的形成,也可能在融合中起直接作用。此外,SNARE复合物的组装可能是由Munc 13和RIMs精心策划的,它们是在囊泡引发和多种形式的突触前可塑性中起作用的活性区蛋白。突触结合蛋白-1介导触发释放的钙离子,可能通过与SNARE和两个膜的相互作用,以及通过紧密的相互作用与复合蛋白。阐明释放机制将需要充分了解所有这些蛋白质和膜之间的相互作用网络。
The core of the neurotransmitter release machinery is formed by SNARE complexes, which bring the vesicle and plasma membranes together and are key for fusion, and by Munc18-1, which controls SNARE-complex formation and may also have a direct role in fusion. In addition, SNARE complex assembly is likely orchestrated by Munc13s and RIMs, active-zone proteins that function in vesicle priming and diverse forms of presynaptic plasticity. Synaptotagmin-1 mediates triggering of release by Ca2+, probably through interactions with SNAREs and both membranes, as well as through a tight interplay with complexins. Elucidation of the release mechanism will require a full understanding of the network of interactions among all these proteins and the membranes.
