最近,人们对mRNA中稳定的G-四链体结构的形成及其功能意义的兴趣大增。在神经元中,mRNA的局部翻译对于正常的神经元行为是必不可少的。已经发现,编码一些最著名的突触蛋白的特定mRNA的局部翻译依赖于G-四链体的存在。mRNA中G-四链体的识别、它们作为抑制复合物的转运以及它们在亚细胞目的地的翻译控制涉及多种蛋白质,包括与疾病病理学相关的蛋白质。这是一个令人兴奋的领域,随着我们的知识和理解的迅速提高。在这里,我们讨论了一些最近的工作如何G-四链体介导的神经元中的本地翻译。
There has recently been a huge increase in interest in the formation of stable G-quadruplex structures in mRNAs and their functional significance. In neurons, local translation of mRNA is essential for normal neuronal behaviour. It has been discovered that local translation of specific mRNAs encoding some of the best known synaptic proteins is dependent on the presence of a G-quadruplex. The recognition of G-quadruplexes in mRNAs, their transport as repressed complexes and the control of their translation at their subcellular destinations involves a diversity of proteins, including those associated with disease pathologies. This is an exciting field, with rapid improvements to our knowledge and understanding. Here, we discuss some of the recent work on how G-quadruplexes mediate local translation in neurons.
