基因组的完整性不断受到损伤DNA的内在和外在遗传毒性应激的挑战。细胞对DNA损伤的反应是由DNA损伤信号通路(也称为DNA损伤检查点)协调的。这些信号通路在检测DNA损伤、调节DNA修复以及协调DNA修复与其他细胞过程中起着至关重要的作用。在脊椎动物中,ATM和Rad3相关(ATR)激酶在对广谱DNA损伤和DNA复制应激的反应中起着关键作用。在这篇文章中,我们将讨论ATR如何被DNA损伤激活的最新发现,以及它如何保护基因组免受DNA复制的干扰。
The integrity of the genome is constantly challenged by intrinsic and extrinsic genotoxic stresses that damage DNA. The cellular responses to DNA damage are orchestrated by DNA damage signaling pathways, also known as DNA damage checkpoints. These signaling pathways play crucial roles in detecting DNA damage, regulating DNA repair, and coordinating DNA repair with other cellular processes. In vertebrates, the ATM- and Rad3-related (ATR) kinase plays a key role in the response to a broad spectrum of DNA damage and DNA replication stress. In this article, we will discuss the recent findings on how ATR is activated by DNA damage, and how it protects the genome against interference with DNA replication.
