对RNA腺苷碱基(M6A)甲基化作用的研究最近才开始,但很快就发现m6A能够控制和微调mRNA的许多方面,从剪接到翻译。由于突触选择性蛋白质翻译的影响,m6A在远端调节翻译的能力很快引起了神经学家的注意,因为m6A在核附近的传统位置调节翻译。在大脑中的研究已经证明了m6A在许多神经元功能中是如何发挥作用的,但这里特别详细地介绍了两个:m6A在1)神经元发育中的作用;以及2)记忆的形成。这篇综述的目的并不是要涵盖大脑中有关m6A的所有数据。相反,这篇综述将集中在m6A功能在神经元发育中的联系机制,以及m6A在记忆形成中的已知功能。我们将介绍“翻译启动”的概念,并讨论当前数据如何适应这一模型,然后推测记忆巩固过程中m6A介导的翻译启动如何在突触局部调节学习和记忆。
Investigation into the role of methylation of the adenosine base (m6A) of RNA has only recently begun, but it quickly became apparent that m6A is able to control and fine-tune many aspects of mRNA, from splicing to translation. The ability of m6A to regulate translation distally, away from traditional sites near the nucleus, quickly caught the eye of neuroscientists because of implications for selective protein translation at synapses. Work in the brain has demonstrated how m6A is functionally required for many neuronal functions, but two in particular are covered at length here: The role of m6A in 1) neuron development; and 2) memory formation. The purpose of this review is not to cover all data about m6A in the brain. Instead, this review will focus on connecting mechanisms of m6A function in neuron development, with m6A’s known function in memory formation. We will introduce the concept of “translational priming” and discuss how current data fit into this model, then speculate how m6A-mediated translational priming during memory consolidation can regulate learning and memory locally at the synapse.
