研究方向:

  真核生物的多种生命活动,如DNA复制、基因转录、DNA损伤修复、基因组稳定性维持等,均受到表观遗传机制的调控。染色质的动态变化调节DNA的折叠方式,是表观遗传调控的重要基础。DNA和组蛋白的分子结构、组成形式的改变能够造成染色质结构的动态变化,并与众多表观因子(如组蛋白变体、组蛋白伴侣、组蛋白修饰酶、染色质重塑复合物、非编码RNA等)一起调控染色质动态,确保生命活动的有序进行。本课题组致力于研究染色质动态的调控及其表观遗传功能。其主要发现包括组蛋白变体的识别机制、"核小体编辑"的基本规律、DNA损伤修复途径的决定机制等。

  "核小体编辑"是染色质重构复合物催化组蛋白变体H2A.Z替换常规H2A,并将H2A.Z精准定位到基因组特定区域的过程,其功能异常与癌症等多种疾病密切相关。我们希望阐明核小体编辑的作用机制,实现核小体编辑的人工操控(图一)。细胞对DNA损伤修复途径的决定机制对于基因组稳定性维持至关重要,DNA损伤"合成致死"效应的发现,催生了PAPR抑制剂等一线抗癌药物。我们希望研究细胞选择不同修复途径进行DNA损伤修复的作用机制,寻找新的药物靶点用于抗癌药物的研发(图二)。

  我们将运用结构生物学、生物化学、生物物理学、酵母遗传学、单分子力谱等方法开展上述研究。
