Mitophagy Where Parkin Parks

Damaged mitochondria are removed from cells in a process known as mitophagy. Failure of this quality-control mechanism contributes to Parkinson’s disease. When damaged mitochondria lose membrane depolarization, the protein kinase, PINK1, accumulates on the mitochondrial surface, recruits Parkin, and promotes mitophagy. Chen and Dorn describe another component of this process, mitofusin 2, which appears to function as the receptor for Parkin on the surface of damaged mitochondria.

Y. Chen, G. W. Dorn II, PINK1-phosphorylated mitofusin 2 is a Parkin receptor for culling damaged mitochondria. Science 340, 471–475 (2013). [Abstract] [Full Text]
