突触传递依赖于精确调控和超快的蛋白质-蛋白质相互作用,涉及电压门控通道、胞吐/内吞机制以及信号通路。虽然我们已经对突触的结构有了更详细的了解,但关于突触是如何维持的,仍有许多有待了解。突触伴侣蛋白是一种“折叠催化剂”,通过调节蛋白质构象(从而调节蛋白质功能)来维持蛋白质的稳定性,并防止不必要的蛋白质相互作用。突触不能维持是几种退行性疾病的早期特征。半胱氨酸串蛋白(Cspα)是一种突触前囊泡蛋白和分子伴侣,在防止突触丢失和神经退行性变中起核心作用。在过去的几年里,许多不同的“客户蛋白”被认为是CSPα的底物,包括电压依赖的离子通道、信号蛋白和突触小泡周期的关键蛋白。在这里,我们回顾了离子通道和突触蛋白复合体在CSPα的影响下,并讨论了我们目前的知识差距。
Synaptic transmission relies on precisely regulated and exceedingly fast protein-protein interactions that involve voltage-gated channels, the exocytosis/endocytosis machinery as well as signaling pathways. Although we have gained an ever more detailed picture of synaptic architecture much remains to be learned about how synapses are maintained. Synaptic chaperones are “folding catalysts” that preserve proteostasis by regulating protein conformation (and therefore protein function) and prevent unwanted protein-protein interactions. Failure to maintain synapses is an early hallmark of several degenerative diseases. Cysteine string protein (CSPα) is a presynaptic vesicle protein and molecular chaperone that has a central role in preventing synaptic loss and neurodegeneration. Over the past few years, a number of different “client proteins” have been implicated as CSPα substrates including voltage-dependent ion channels, signaling proteins and proteins critical to the synaptic vesicle cycle. Here we review the ion channels and synaptic protein complexes under the influence of CSPα and discuss gaps in our current knowledge.
