Abstract
Dysfunctions in mitophagy, the process by which mitochondria are eliminated, are associated with cancer. We found that the proautophagic protein AMBRA1 (activating molecule in beclin 1 regulated autophagy) binds the autophagosome adapter LC3, and that this interaction is crucial for mitochondrial clearance with or without involvement of the E3-ligase PARKIN. The discovery of a novel mitophagy pathway has the potential to promote new anticancer strategies.
