DUBs counteract parkin for efficient mitophagy

Ivan Dikic et al. EMBO J. .

Abstract

The Parkinson's disease-associated ubiquitin E3 ligase parkin impacts various cellular processes including the autophagic clearance of defective mitochondria. In this issue of The EMBO Journal, Durcan et al (2014) reveal a novel control mechanism of parkin-mediated mitophagy via the selective removal of atypical K6-linked ubiquitin chains from parkin by the deubiquitinase USP8. Together with recent studies on USP15 and USP30, this establishes a functional role for deubiquitination in mitophagy regulation.
