研究方向
本课题组主要开展蛋白质化学生物学研究。通过发展适用于活细胞及活体动物的新型生物正交反应(尤其是断键反应),“在体”研究蛋白质的动态修饰及在细胞性状调控中的功能,开发基于蛋白质的靶向干预新途径。具体的研究内容和科学问题集中在以下三个方面:(1)发展生物正交剪切反应及相应的化学脱笼技术,用于在活细胞及活体动物内特异激活信号转导的关键调控酶(如磷酸激酶),高时空分辨地研究由信号转导蛋白的动态修饰介导的细胞性状调控。(2)发展可遗传编码的多功能光交联探针,用于捕捉参与表观遗传调控的关键蛋白-蛋白相互作用(如组蛋白与修饰酶),发现组蛋白动态修饰的新型催化酶及识别蛋白,解析其调控细胞性状的分子机制。(3)基于蛋白质和多肽的药物开发,发展靶向干预细胞性状变化(如癌变)的蛋白质及多肽分子,解决这些潜在药物的靶向递送、原位释放(前药)等问题。
