Omegasome-proximal PtdIns(4,5)P2 couples F-actin mediated mitoaggregate disassembly with autophagosome formation during mitophagy

Abstract

Autophagic cells coordinate substrate remodeling with sequestration during autophagosome formation. Here, the authors show that during Parkin-mediated mitophagy, mitochondria are disassembled into progressively smaller aggregates near autophagy initiation sites in a PtdIns(4,5)P2-dependent manner.
