Mutations in parkin are the second most common known cause of Parkinson's disease (PD). Parkin is an ubiquitin E3 ligase that monoubiquitinates and polyubiquitinates proteins to regulate a variety of cellular processes. Loss of parkin's E3 ligase activity is thought to play a pathogenic role in both inherited and sporadic PD. Here, we review parkin biology and pathobiology and its role in the pathogenesis of PD.
Parkin 基因突变是仅次于帕金森病(PD)的第二大常见原因。Parkin 是一种泛素 E3 连接酶,可单泛素化和多泛素化蛋白质,以调节多种细胞过程。Parkin 的 E3 连接酶活性丧失被认为在遗传性和散发性 PD 中都起着致病作用。在这里,我们回顾了 Parkin 的生物学和病理生物学及其在 PD 发病机制中的作用。
