protein receptor on the surface of the mitochondrial membrane that recruits DRP1 protein to induce mitochondrial binary fission. By targeting the protein–protein interaction of DRP1/MiD49, we have discovered a novel and potent allosteric DRP1 inhibitor that inhibits mitochondria fragmentation in vitro. X-ray cocrystal structure revealed that it locked the closed DRP1 conformation by induced dimerization
线粒体功能障碍可归因于许多疾病适应症,包括代谢性疾病、心血管疾病、肿瘤疾病和神经退行性疾病。 Dynamin 相关蛋白 1 (DRP1) 对于调节线粒体裂变和维持线粒体稳态至关重要。 Mi
D49 是线粒体膜表面的动态外周蛋白受体,可招募 DRP1 蛋白诱导线粒体二元裂变。通过靶向 DRP1/Mi
D49 的蛋白质-蛋白质相互作用,我们发现了一种新型有效的变构 DRP1
抑制剂,可在体外抑制线粒体断裂。 X射线共晶结构表明它通过诱导二聚化锁定了闭合的DRP1构象。
