Eukaryotic cells have developed conserved mechanisms to efficiently sense and repair DNA damage that results from constant chromosomal lesions. DNA repair has to proceed in the context of chromatin, and both histone-modifiers and ATP-dependent chromatin remodelers have been implicated in this process. Here, we review the current understanding and new hypotheses on how different chromatin-modifying activities function in DNA repair in yeast and metazoan cells.
真核细胞已经进化出保守机制,以有效感知和修复由持续的染色体损伤导致的DNA损伤。DNA修复必须在染色质的背景下进行,组蛋白修饰因子和ATP依赖的染色质重塑因子都参与了这一过程。在这里,我们综述了目前对于酵母和后生动物细胞中不同染色质修饰活性如何在DNA修复中发挥作用的理解以及新的假说。
