朱卫国教授团队在《Nature Structural & Molecular Biology》发文揭示DNA损伤修复起始阶段染色质乙酰化的调控新机制（图）
DNA 朱卫国教授 生物学 赖氨酸
2023/10/23
DNA损伤应答与修复经历“进入-修复-恢复” (Access-Repair-Restore，ARR）三个生物学过程。核小体稳态对于DNA损伤应答及信号解除、基因转录瞬时激活与抑制至关重要。单就组蛋白赖氨酸乙酰化来说，乙酰化介导染色质松弛以便DNA修复推进或促进基因转录；去乙酰化则造成致密染色质结构以保护遗传物质不受损失或抑制基因转录，因此染色质松散被认为是DNA双链断裂修复（DSBs）的先决条件。...
