教师简介：
染色质是细胞生命的核心，在生理、病理和药理研究中处于基础地位。虽然细胞染色质的结构变化和功能调节是动态的，但是探测其在纳米精度上的实时动态分子事件极具挑战。于仲波课题组围绕染色质的结构与功能，开发了能够实时精密探测分子相互作用的单分子技术，应用到核酸蛋白互作、蛋白蛋白互作、以及干预分子互作的药物开发等领域。譬如，细胞间期Shelterin等蛋白复合体压缩染色质的端粒，保护端粒免受DNA损伤修复机制的攻击，但是，压缩的端粒也需要解压缩，从而允许发生复制、延长和转录等重大事件。 如果我们能够实时精密探测端粒压缩和解压缩的动态过程，解析其中的分子动作，就能够深入理解端粒的分子生物学机制，从而设计针对端粒分子事件的药物靶点，为衰老、肿瘤、慢性病等端粒相关疾病开发全新的药物。又如，表观遗传因子调控DNA和组蛋白的甲基化和去甲基化修饰，但是酶促反应的分子机制不明。以MLL1 PHD3-Bromo为例，我们可以运用单分子互作技术，构建PHD3-Bromo与核小体组蛋白互作的单分子反应，解析二者互作的单分子动态机制，为开发靶向药物提供单分子反应平台。
