PINK1 points Parkin to mitochondria [PDF]

Autophagy, 2010
For decades, it has been presumed that mitochondrial dysfunction, in the form of impaired complex I activity, may contribute to the cause of Parkinson disease (PD). ( 1) The discovery that several gene mutations cause familial forms of PD ( 1) has led to a renewed enthusiasm for the mitochondrial hypothesis of PD, but this time from a quite distinct ...

Mitochondrial dynamics–fusion, fission, movement, and mitophagy–in neurodegenerative diseases [PDF]

, 2009
Neurons are metabolically active cells with high energy demands at locations distant from the cell body. As a result, these cells are particularly dependent on mitochondrial function, as reflected by the observation that diseases of mitochondrial ...

Pink1 and Parkin regulate Drosophila intestinal stem cell proliferation during stress and aging. [PDF]

, 2017
Intestinal stem cells (ISCs) maintain the midgut epithelium in Drosophila melanogaster Proper cellular turnover and tissue function rely on tightly regulated rates of ISC division and appropriate differentiation of daughter cells.

Panax notoginseng Saponins Attenuate Cerebral Ischemia-Reperfusion Injury via Mitophagy-Induced Inhibition of NLRP3 Inflammasome in Rats

Frontiers in Bioscience-Landmark, 2022
Background: The mitophagy/NLRP3 inflammasome pathway is a promising therapeutic target for cerebral ischemia-reperfusion (I/R). Panax notoginseng (Burkill) F.H.

Synergistic recruitment of UbcH7~Ub and phosphorylated Ubl domain triggers parkin activation [PDF]

, 2018
The E3 ligase parkin ubiquitinates outer mitochondrial membrane proteins during oxidative stress and is linked to early-onset Parkinson’s disease. Parkin is autoinhibited but is activated by the kinase PINK1 that phosphorylates ubiquitin leading to ...

HIF1α-dependent mitophagy facilitates cardiomyoblast differentiation [PDF]

, 2020
Mitophagy is thought to play a key role in eliminating damaged mitochondria, with diseases such as cancer and neurodegeneration exhibiting defects in this process.

Pink1, the first ubiquitin kinase [PDF]

The EMBO Journal, 2014
Pink1 and Parkin, identified through studies of hereditary early onset Parkinson's disease, are involved in mitochondria quality control. Parkin E3 ubiquitin ligase activity is activated by Pink1 kinase activity, although the mechanism is still elusive. Three recent reports uncover a surprising mechanism in which Pink1 directly phosphorylates ubiquitin

Phosphorylation of Parkin at serine 65 is essential for its activation in vivo [PDF]

Open Biology, 2018
Mutations in PINK1 and Parkin result in autosomal recessive Parkinson's disease (PD). Cell culture and in vitro studies have elaborated the PINK1-dependent regulation of Parkin and defined how this dyad orchestrates the elimination of damaged ...

Broad activation of the ubiquitin-proteasome system by Parkin is critical for mitophagy [PDF]

, 2011
Parkin, an E3 ubiquitin ligase implicated in Parkinson's disease, promotes degradation of dysfunctional mitochondria by autophagy. Using proteomic and cellular approaches, we show that upon translocation to mitochondria, Parkin activates the ubiquitin ...

PINK1 mutations and parkinsonism [PDF]

Neurology, 2008
PINK1 loss-of-function causes recessive, early-onset parkinsonism. In Tunisia there is a high rate of consanguineous marriage but PINK1 carrier frequency and disease prevalence have yet to be assessed.The frequency of PINK1 mutations in familial parkinsonism, community-based patients with idiopathic Parkinson disease (PD) (non-familial PD), and control
