WebApr 1, 2024 · Interestingly, PINK1 may also generate p-Ub and recruit NDP52/OPTN independently of Parkin to drive low-level mitophagy, implying the involvement of additional ubiquitin E3 ligases [21 •]. Until recently, it was widely assumed that the ATG-conjugation machinery is crucial for autophagosome biogenesis and cargo incorporation. 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 …
WebApr 19, 2024 · Finally, through modulation of pS65-Ub on mitochondria, we demonstrate that Ub hyper-phosphorylation is inhibitory to mitophagy receptor recruitment, indicating that pS65-Ub stoichiometry in vivo is optimized to coordinate PARKIN recruitment via pS65-Ub and mitophagy receptors via unphosphorylated chains. WebOct 12, 2024 · Here we show that like Ub, NEDD8 is phosphorylated by PINK1 at S65 and that pNEDD8 stimulates PINK1-mediated Parkin phosphorylation and in addition acts as …
