Mitophagy is an important housekeeping function in eukaryotic cells, and defects in mitophagy correlate with ageing phenomena and with several neurodegenerative disorders. Here we combine a proteomic study with a molecular genetics and cell biology approach to determine whether such a segregation process occurs in yeast mitochondria. We find that different mitochondrial matrix proteins undergo mitophagic degradation at distinctly different rates, supporting the active segregation hypothesis.
