令人信服的证据表明,两个常染色体隐性帕金森病基因PINK1 (PARK6)和Parkin (PARK2)协同介导受损线粒体的自噬清除(线粒体自噬)。含有Fbxo7蛋白(PARK15)的F-box结构域的突变也通过一种未知的机制导致早发性常染色体隐性帕金森病。本研究表明Fbxo7通过与PINK1和Parkin的直接相互作用参与线粒体维持,并在Parkin介导的线粒体自噬中发挥作用。Fbxo7表达降低的细胞显示Parkin线粒体易位、丝裂酶1泛素化和丝裂作用的缺陷。在果蝇中,Fbxo7的异位过表达挽救了Parkin的缺失,支持了两种蛋白之间的功能关系。引起帕金森病的Fbxo7突变干扰了这一过程,强调了线粒体功能障碍在帕金森病发病机制中的重要性。
Compelling evidence indicates that two autosomal recessive Parkinson’s disease genes, PINK1 (PARK6) and Parkin (PARK2), co-operate to mediate the autophagic clearance of damaged mitochondria (mitophagy). Mutations in the F-box domain containing protein Fbxo7 (PARK15) also cause early onset autosomal recessive Parkinson’s disease by an unknown mechanism. Here we show that Fbxo7 participates in mitochondrial maintenance through direct interaction with PINK1 and Parkin and plays a role in Parkin-mediated mitophagy. Cells with reduced Fbxo7 expression show deficiencies in Parkin mitochondrial translocation, ubiquitination of mitofusin 1 and mitophagy. In Drosophila, ectopic overexpression of Fbxo7 rescued loss of Parkin supporting a functional relationship between the two proteins. Parkinson’s disease-causing mutations in Fbxo7 interfere with this process, emphasising the importance of mitochondrial dysfunction in Parkinson’s disease pathogenesis.
