真核细胞中的DNA修复是在染色质的背景下进行的,在染色质中,DNA,包括受损的DNA,紧密地聚集在核小体和更高阶的染色质结构中。染色质本质上限制了DNA修复蛋白对受损DNA的可及性,并影响DNA修复的总体速度。染色质对DNA损伤高度敏感,并经历特定的重塑以促进DNA修复。受损的DNA是如何进入、修复和恢复到原始染色质状态的,以及在体内染色质重塑如何协调这些过程,在很大程度上仍是未知的。依赖于ATP的染色质重构体(ACRs)是染色质结构和动力学的主要调节因子。ACRs从酵母到人类都是保守的,它利用三磷酸腺苷的能量重组染色质的堆积,并通过滑动、弹射或重组核小体来控制DNA的可及性。一些研究表明,ACRs的ATP依赖性重塑活动在协调染色质不同DNA修复途径的时空步骤中发挥着重要作用。本文就ACRs在染色质中核苷酸切除修复(NER)的各个方面的调控作用作一综述。我们讨论了目前对ATP依赖的染色质重塑的理解,以及体内NER通路的调节。
DNA repair in eukaryotic cells takes place in the context of chromatin, where DNA, including damaged DNA, is tightly packed into nucleosomes and higher order chromatin structures. Chromatin intrinsically restricts accessibility of DNA repair proteins to the damaged DNA and impacts upon the overall rate of DNA repair. Chromatin is highly responsive to DNA damage and undergoes specific remodeling to facilitate DNA repair. How damaged DNA is accessed, repaired and restored to the original chromatin state, and how chromatin remodeling coordinates these processes in vivo, remains largely unknown. ATP-dependent chromatin remodelers (ACRs) are the master regulators of chromatin structure and dynamics. Conserved from yeast to humans, ACRs utilize the energy of ATP to reorganize packing of chromatin and control DNA accessibility by sliding, ejecting or restructuring nucleosomes. Several studies have demonstrated that ATP-dependent remodeling activity of ACRs plays important roles in coordination of spatio-temporal steps of different DNA repair pathways in chromatin. This review focuses on the role of ACRs in regulation of various aspects of nucleotide excision repair (NER) in the context of chromatin. We discuss current understanding of ATP-dependent chromatin remodeling by various subfamilies of remodelers and regulation of the NER pathway in vivo.
