Mechanism of parkin activation by phosphorylation.

Abstract excerpt

Mutations in the ubiquitin ligase parkin are responsible for a familial form of Parkinson's disease. Parkin and the PINK1 kinase regulate a quality-control system for mitochondria. PINK1 phosphorylates ubiquitin on the outer membrane of damaged mitochondria, thus leading to recruitment and activation of parkin via phosphorylation of its ubiquitin-like (Ubl) domain. Here, we describe the mechanism of parkin...
