Non-homologous end joining (NHEJ) is the preferred pathway for the repair of DNA double-strand breaks in humans. Here we describe three structural aspects of the repair pathway: stages, scaffolds and strings. We discuss the orchestration of DNA repair to guarantee robust and efficient NHEJ. We focus on structural studies over the past two decades, not only using X-ray diffraction, but also increasingly exploiting cryo-EM to investigate the macromolecular assemblies.
非同源末端连接(NHEJ)是人类修复 DNA 双链断裂的首选途径。在这里,我们描述了修复途径的三个结构方面:阶段、支架和字符串。我们讨论了 DNA 修复的协调,以保证强大和有效的 NHEJ。我们专注于过去二十年的结构研究,不仅使用 X 射线衍射,而且越来越多地利用 cryo-EM 来研究大分子组装。
