A PINK1 input threshold arises from positive feedback in the PINK1/Parkin mitophagy decision circuit

Cell Reports, 2023
Summary: Mechanisms that prevent accidental activation of the PINK1/Parkin mitophagy circuit on healthy mitochondria are poorly understood. On the surface of damaged mitochondria, PINK1 accumulates and acts as the input signal to a positive feedback loop

Mechanism of parkin activation by PINK1 [PDF]

Nature, 2018
Mutations in the E3 ubiquitin ligase parkin (PARK2, also known as PRKN) and the protein kinase PINK1 (also known as PARK6) are linked to autosomal-recessive juvenile parkinsonism (AR-JP)1,2; at the cellular level, these mutations cause defects in mitophagy, the process that organizes the destruction of damaged mitochondria3,4.

Drosophila Parkin requires PINK1 for mitochondrial translocation and ubiquitinates Mitofusin [PDF]

, 2010
Loss of the E3 ubiquitin ligase Parkin causes early onset Parkinson's disease, a neurodegenerative disorder of unknown etiology. Parkin has been linked to multiple cellular processes including protein degradation, mitochondrial homeostasis, and autophagy;

PINK1/PARKIN signalling in neurodegeneration and neuroinflammation [PDF]

Acta Neuropathologica Communications, 2020
Abstract Mutations in the PTEN-induced kinase 1 (PINK1) and Parkin RBR E3 ubiquitin-protein ligase (PARKIN) genes are associated with familial forms of Parkinson’s disease (PD). PINK1, a protein kinase, and PARKIN, an E3 ubiquitin ligase, control the specific elimination of dysfunctional or superfluous mitochondria, thus fine-tuning ...

TSPO interacts with VDAC1 and triggers a ROS-mediated inhibition of mitochondrial quality control [PDF]

, 2014
The 18-kDa TSPO (translocator protein) localizes on the outer mitochondrial membrane (OMM) and participates in cholesterol transport. Here, we report that TSPO inhibits mitochondrial autophagy downstream of the PINK1-PARK2 pathway, preventing essential ...

The Effect of Combined Resistance-Aerobic Training Along with Olive Oil Consumption on some Genes Involved in Apoptosis and the Balance of Induced Parkinsonian Rats

Journal of Ardabil University of Medical Sciences, 2022
Background & objectives: Parkinson's disease is a progressive neurological disorder associated with the destruction of dopaminergic neurons in the substantia nigra. Physical exercise can control the risk of neuronal damage.

Mitochondrial-Dependent and Independent Functions of PINK1

Frontiers in Cell and Developmental Biology, 2022
PINK1 has been characterized as a mitochondrial kinase that can target to damaged mitochondria to initiate mitophagy, a process to remove unhealthy mitochondria for protecting neuronal cells.
