E3 ubiquitin ligase
How Mitochondrial Dynamism Orchestrates Mitophagy.
Beersheba, Israel. In Circ Res, 22 Jun 2015
Here, we review accumulating evidence supporting important roles for mitochondrial fission and fusion in cardiac mitochondrial quality control, focusing on the PTEN-induced putative kinase 1-Parkin mitophagy pathway.
Quantifying Ubiquitin Signaling.
Boston, United States. In Mol Cell, 21 Jun 2015
Here, we review how quantitative proteomic tools and enrichment strategies are being used to quantify UB-dependent signaling systems, and to integrate UB signaling with regulatory phosphorylation events, illustrated with the PINK1/PARKIN pathway.
The mitochondrial deubiquitinase USP30 opposes parkin-mediated mitophagy.
San Francisco, United States. In Nature, Jul 2014
Here we report that USP30, a deubiquitinase localized to mitochondria, antagonizes mitophagy driven by the ubiquitin ligase parkin (also known as PARK2) and protein kinase PINK1, which are encoded by two genes associated with Parkinson's disease.
Pan-cancer genetic analysis identifies PARK2 as a master regulator of G1/S cyclins.
New York City, United States. In Nat Genet, Jun 2014
The PARK2 E3 ubiquitin ligase coordinately controls the stability of both cyclin D and cyclin E. Analysis of approximately 5,000 tumor genomes shows that PARK2 is a very frequently deleted gene in human cancer and uncovers a striking pattern of mutual exclusivity between PARK2 deletion and amplification of CCND1, CCNE1 or CDK4-implicating these genes in a common pathway.
PARK2 orchestrates cyclins to avoid cancer.
Praha, Czech Republic. In Nat Genet, Jun 2014
A new study identifies the PARK2 E3 ubiquitin ligase as an important coordinator of G1/S-phase cyclin turnover and explains how mutations targeting this key cell cycle regulatory node contribute to a range of cancers.
