PARK2/Parkin becomes critical when DNM1L/Drp1 is absent

Autophagy. 2015;11(3):573-4. doi: 10.1080/15548627.2015.1017193.

Abstract

Maintaining mitochondrial dynamics and proper execution of mitophagy is crucial for sustaining cellular health. Defects in these processes have been linked to cardiovascular diseases and neurodegeneration. In a recent publication, we reported that the mitochondrial division dynamin protein DNM1L/Drp1 and the E3 ubiquitin ligase PARK2/Parkin work in a synergistic manner to maintain mitochondrial function and structural integrity in the mouse heart and brain.

Keywords: Drp1; Parkin; mitochondrial dynamics; mitochondrial homeostasis; mitophagy.
