In Parkin (a Parkinson-disease-associated ubiquitin ligase that can trigger depolarized-mitochondrion mitophagy) -mediated mitophagy, the structures containing Atg9A and the ULK1-complex are independently recruited to depolarized mitochondria and both are required for further recruitment of downstream Atg proteins, except LC3. Here, PRKN is linked to Parkinson disease.
