abstract = {Mitophagy, the selective degradation of mitochondria by
autophagy, affects defective mitochondria following damage
or stress. At the onset of mitophagy, parkin ubiquitylates
proteins on the mitochondrial outer membrane. While the role
of parkin at the onset of mitophagy is well understood, less
is known about its activity during later stages in the
process. Here, we used HeLa cells expressing catalytically
active or inactive parkin to perform temporal analysis of
the proteome, ubiquitylome, and phosphoproteome during 18 h
after induction of mitophagy by mitochondrial uncoupler
carbonyl cyanide m-chlorophenyl hydrazine. Abundance
profiles of proteins downregulated in parkin-dependent
manner revealed a stepwise and 'outside-in' directed
degradation of mitochondrial subcompartments. While
ubiquitylation of mitochondrial outer membrane proteins was
enriched among early parkin-dependent targets, numerous
mitochondrial inner membrane, matrix, and cytosolic proteins
were also found ubiquitylated at later stages of mitophagy.
Phosphoproteome analysis revealed a possible crosstalk
between phosphorylation and ubiquitylation during mitophagy
on key parkin targets, such as voltage-dependent anion
channel 2.},
