New regulators of PRKN-independent mitophagy
Yuchen Lei, Daniel J. Klionsky
Abstract
Mitophagy, a type of selective autophagy targeting damaged or superfluous mitochondria, is critical to maintain cell homeostasis. Besides the well-characterized PRKN-dependent mitophagy, PRKN-independent mitophagy also plays significant physiological roles. In a recent study, researchers from Anne Simonsen’s lab discovered two lipid binding kinases, GAK and PRKCD, as positive regulators of PRKN-independent mitophagy. The researchers further investigated how these two proteins regulate mitophagy and demonstrated their roles in vivo. Focusing on the less known PRKN-independent mitophagy regulators, these findings shed light on understanding the mechanism of mitophagy and its relation to diseases.
