DNA胞嘧啶5-甲基化修饰是表观遗传重要的修饰之一,其对基因表达的调控依赖下游的识别蛋白识别和传递甲基化信号.本文围绕两种主要的甲基化DNA识别结构域——MBD结构域和SRA结构域,综述了它们识别不同修饰形式DNA的结构基础以及发挥功能的分子机理.
DNA methylation at the 5 position of cytosine is one of the most important epigenetic modifications in vertebrate, which regulate gene expression in conjunction with specific protein readers to readout the methyl marks. This review focuses on two major classes of methyl DNAreaders, MBD and SRA domains, and discusses their structural bases and molecular mechanisms of recognizing different types of DNA modification marks.
