为了防止DNA链断裂造成的损伤,真核细胞已经进化出一系列高度保守的DNA修复机制。广泛表达的乙酰转移酶Tip 60在参与DNA修复的ATM(共济失调-毛细血管扩张突变)激活中起核心作用。最近的工作揭示了Tip 60介导的ATM激活的新机制,并证明组蛋白甲基化,特别是组蛋白H3的三甲基化,是该过程中的关键因素。在这里,我们回顾了目前对Tip 60如何激活以及它如何激活ATM以响应DNA损伤的理解。
To prevent the damage caused by DNA strand breaks, eukaryotic cells have evolved a series of highly conserved DNA repair mechanisms. The ubiquitously expressed acetyltransferase, Tip60, plays a central role in ATM (ataxia-telangiectasia mutated) activation which is involved in DNA repair. Recent work uncovered a new mechanism of ATM activation mediated by Tip60 and demonstrated that histone methylation, specifically, trimethylation of histone H3, is a key factor in the process. Here, we review the current understanding of how Tip60 is activated and how it activates ATM in response to DNA damage.
