Journal ArticleDOI
Parkin is recruited selectively to impaired mitochondria and promotes their autophagy
TL;DR: It is shown that Parkin is selectively recruited to dysfunctional mitochondria with low membrane potential in mammalian cells and this recruitment promotes autophagy of damaged mitochondria and implicate a failure to eliminate dysfunctional mitochondira in the pathogenesis of Parkinson's disease.
Journal ArticleDOI
PINK1 is selectively stabilized on impaired mitochondria to activate Parkin.
Derek P. Narendra,Seok Min Jin,Atsushi Tanaka,Der-Fen Suen,Clement A. Gautier,Jie Shen,Mark R. Cookson,Richard J. Youle +7 more
TL;DR: The authors suggest that PINK1 and Parkin form a pathway that senses damaged mitochondria and selectively targets them for degradation.
Journal ArticleDOI
Proteasome and p97 mediate mitophagy and degradation of mitofusins induced by Parkin
Atsushi Tanaka,Megan M. Cleland,Shan-Shan Xu,Derek P. Narendra,Der-Fen Suen,Mariusz Karbowski,Richard J. Youle +6 more
TL;DR: The Parkin ubiquitin ligase marks the mitofusins Mfn1 and Mfn2 for proteasome-dependent degradation, promoting disposal of damaged mitochondria by preventing their fusion with healthy organelles.
Journal ArticleDOI
Parkin overexpression selects against a deleterious mtDNA mutation in heteroplasmic cybrid cells
TL;DR: Long-term overexpression of Parkin can eliminate mitochondria with deleterious COXI mutations in heteroplasmic cybrid cells, thereby enriching cells for wild-type mtDNA and restoring cytochrome c oxidase activity, and support the model that Parkin functions in a mitochondrial quality control pathway.
Journal ArticleDOI
Parkin-induced mitophagy in the pathogenesis of Parkinson disease.
TL;DR: Findings suggest that Parkin promotes mitophagy of dysfunctional mitochondria following loss of mitochondrial membrane potential and implicate the targeted elimination of mitochondria in the pathogenesis of Parkinson disease.
