Drp1 cuts off mitophagy
Misfolded mitochondrial proteins can be eliminated by Parkin-dependent mitophagy but how this process selectively removes damaged mitochondrial regions is unclear. Burman et al. reveal that protein aggregates in the mitochondrial matrix trigger a local accumulation of Parkin on the mitochondrial outer membrane, and that the mitochondrial fission protein Drp1 segregates these domains to prevent Parkin accumulation from spreading and directing the elimination of healthy regions of the organelle. This biosights episode presents the paper by Burman et al. from the October 2nd, 2017, issue of The Journal of Cell Biology and includes an interview with the paper's senior author, Richard Youle (NINDS, NIH). Produced by Caitlin Sedwick and Ben Short. See the associated paper in JCB for details on the funding provided to support this original research.
