Parkin is dispensable for mitochondrial function, but its ubiquitin ligase activity is critical for macroautophagy and neurotransmitters: therapeutic potential beyond Parkinson's disease

Moussa, Charbel E.-H.·2015·Neurodegenerative Diseases

Abstract

Parkin biology has emerged as an exciting area of pharmaceutical development for several human diseases, including cancer and neurodegeneration. Parkin's role is multifaceted in human health and disease and its function affecting major cellular quality control mechanisms, including the ubiquitin-proteasome and autophagy-lysosome systems, is critical in the maintenance of cellular homeostasis. Loss of Parkin function due to aging, protein instability and gene mutations is manifest in a number of human diseases, contributing to the validation of this protein as a therapeutic target. Parkin activation to mobilize cellular quality control mechanisms and counteract dyshomeostasis is a highly desirable area for therapeutic development. The elucidation of Parkin's crystal structure and better understanding of possible posttranslational modifications (i.e. phosphorylation, ubiquitination, etc.) that regulate Parkin's enzymatic activity suggest that this protein is a therapeutic drug target in many human diseases. Here we review Parkin's role in health and disease and discuss the effects of self-ubiquitination and deubiquitination on Parkin activity. This review provides further evidence showing the longitudinal effects of Parkin deletion on mitochondrial function, oxidative stress and neurotransmitter balance in vivo using high-frequency (1)H/(13)C NMR spectroscopy.

  • Reduced mitophagy via Pink1/Parkin-regulated ubiquitination in aged neurons contributes to greater ROS accumulation.

    “Reduced mitophagy associated Pink1- and Parkin-regulated ubiquitination of the outer mitochondrial membrane of damaged mitochondria in aged neurons (79, 99, 140) contribute to a greater accumulation of ROS (81).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
