发动蛋白相关蛋白1(dynamin-related proteinl,Drpl)是调节线粒体分裂的主要蛋白,其活性与翻译后修饰有关,主要包括磷酸化、泛素化、类泛素化以及S-硝基化.在脑缺血时,Drp1被激活并从细胞质向线粒体外膜转位,介导线粒体分裂及受损线粒体的清除,在缺血神经元凋亡、坏死性凋亡、线粒体自噬等病理学过程中起重要作用.线粒体过度分裂或受损线粒体的积聚都会加重神经元损伤.

Dynamin-related protein 1 (Drpl) is a major protein for regulating mitochondrial fission.Its activity is associated with the post-translational modification,mainly including phosphorylation,ubiquitination,sumoylation,and S-nitrosylation.During the cerebral ischemia,Drpl is activated and translocates from the cytoplasm to the mitochondrial outer membrane,mediates mitochondrial fission and eliminates damaged mitochondria.Drpl plays the important roles in the pathological processes of ischemic neuronal apoptosis,necrotic apoptosis,and mitophagy.Excessive mitochondria fission or accumulation of damaged mitochondria will aggravate neuronal injury.
