主要研究蛋白酶体及自噬等蛋白质降解的作用及机制。
蛋白酶体及自噬介导的蛋白质降解参与蛋白稳态调控,其紊乱导致发育异常及疾病发生。主要研究蛋白质降解在凋亡、衰老及精子发生中的作用机制,揭示巨型泛素化酶BIRC6/BRUCE促进自噬标签蛋白LC3-II的前体LC3-I通过PA28r蛋白酶体降解(PNAS, 2019),并阐释BIRC6调控自噬及凋亡间转换的分子机理(Nat Commun., 2024);阐明PA200蛋白酶体维持转录及衰老过程中组蛋白修饰稳定性的表观遗传调控机制(Theranostics,封面文章, 2021;Curr Genomics, 2021;Biological Reviews, 2018;Int. J. Mol. Sci., 2024);发现泛素连接酶Nrdp1及睾丸特异性蛋白酶体亚基a4s分别通过促进自噬相关顶体生成或精母细胞减数分裂中DNA损伤修复时的组蛋白降解以调控精子发生的分子机制(Cells, 2023; JBC, 2021)。以上成果为治疗癌症、不孕不育及衰老相关疾病提供依据。
在此基础上,本课题组还将探索蛋白质降解在糖脂代谢、衰老及肿瘤等生理及病理过程中的作用机理。
