Phosphorylaiton of ub and parkin in mitophagy
WebMar 5, 2024 · Phosphatase and tensin homolog (PTEN)-induced kinase (PINK) and Parkin proteins, whose mutations are associated with familial forms of Parkinson’s disease, are two of the best characterized mitophagy players. They accumulate at ER–mitochondria contact sites and modulate organelles crosstalk. WebJun 22, 2024 · Mitophagy is an important type of selective autophagy for specific elimination of damaged mitochondria. PTEN-induced putative kinase protein 1 (PINK1)-catalyzed phosphorylation of ubiquitin (Ub) plays a critical role in the onset of PINK1-Parkin-mediated mitophagy. Phosphatase and tensin homolog (PTEN)-long (PTEN-L) is a newly …

WebAug 20, 2015 · These phosphorylation events lead to PARKIN recruitment to mitochondria, and activation by an unknown allosteric mechanism. Here we present the crystal structure of Pediculus humanus PARKIN in complex with Ser65-phosphorylated ubiquitin (phosphoUb), revealing the molecular basis for PARKIN recruitment and activation. WebApr 8, 2024 · Mitophagy failure and mitochondrial dysfunction in iPSC-derived cortical neurons obtained from some cell mines and fluids of patients categorized by reduced levels of Parkin and ATG5, which induced an increase in PINK1, LC3, P-S65-Ub, and TOMMO20 in the mitochondria cavity, thus reducing the macroautophagy degradation.

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. WebJul 3, 2014 · Parkin, the ubiquitin ligase that is mutated in Parkinson’s disease, regulates the clearance of damaged mitochondria through selective autophagy (mitophagy). Here, Hollville et al. show that Parkin-dependent mitophagy is regulated by members of the Bcl-2 family, which are more commonly known for their ability to regulate apoptotic cell death.
