中文摘要
DNA甲基化和组蛋白修饰是在每个分化细胞中维持表观遗传状态的表观遗传标记。我们研究了维持和调节DNA甲基化模式的两个关键蛋白的结构和功能;半甲基化DNA结合蛋白UHRF 1和甲基CpG结合结构域蛋白MBD 4。我们的结构和生化数据揭示了UHRF 1对两种组蛋白修饰的组合识别。为MBD 4的多功能碱基识别奠定了结构基础。
英文摘要
DNA methylation and histone modifications are epigenetic marks that maintain an epigenetic state in each differentiated cell. We investigated structures and functions of two key proteins in maintenance and regulation of DNA methylation patterns ; a hemi-methylated DNA binding protein, UHRF1 and one of methyl CpG binding domain proteins, MBD4. Our structural and biochemical data have shed light on a combinatorial recognition of two histone modifications by UHRF1. Furthermore our research have gained structural basis of versatile base recognition of MBD4.
