WebNov 25, 2024 · Ub-dependent mitophagy usually refers to Pink1-Parkin-mediated mitophagy. Upon mitochondrial depolarization, full-length Pink1 accumulates on the OMM and recruits Parkin to the mitochondrial surface. Pink1 triggers Parkin E3 ligase activity through a circuit of modifications including phosphorylation of both Parkin and ubiquitin. WebRotenone treatment led to not only the activation of p38 but also Parkin inactivation and reactive oxygen species (ROS) overproduction in SN4741 cells. Meanwhile, p38 activation regulated Parkin phosphorylation at serine 131 to disrupt Parkin-mediated mitophagy. Notably, both p38 inhibition and Parkin overexpression decreased ROS levels.
