E3 ubiquitin ligase
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.
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.

Budapest, Hungary. In Neuropsychopharmacol Hung, Jun 2014
Parkin (Parkinson juvenile disease protein 2) is a ~52 kDa (426 amino acid) enzyme protein, encoded by PARK2 gene and located on the 6q chromosome.
Parkin and PINK1: much more than mitophagy.
Baltimore, United States. In Trends Neurosci, Jun 2014
In support of this theory, data from multiple PD models have linked Phosphatase and tensin homolog (PTEN)-induced putative kinase 1 (PINK1) and parkin, two recessive PD genes, in a common pathway impacting mitochondrial health, prompting a flurry of research to identify their mitochondrial targets.
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.

In Przegl Lek, Dec 2013
It is believed, that causes of PD are both environmental and genetic factors, associated mainly with mutations in the SNCA and PRKN genes, which may lead to changes in the structure of proteins such as alpha-synuclein (ASN) and Parkin.
Acute focal brain damage alters mitochondrial dynamics and autophagy in axotomized neurons.
Roma, Italy. In Cell Death Dis, Dec 2013
We provided evidence that lesion of a cerebellar hemisphere causes mitochondria depolarization in axotomized precerebellar neurons associated with PTEN-induced putative kinase 1 accumulation and Parkin translocation to mitochondria, block of mitochondrial fusion by Mfn1 degradation, increase of calcineurin activity and dynamin-related protein 1 translocation to mitochondria, and consequent mitochondrial fission.
Genetics of Parkinson's disease - a clinical perspective.
Pusan, South Korea. In J Mov Disord, 2012
Discovering genes following Medelian inheritance, such as autosomal dominant-synuclein and leucine-rich repeat kinase 2 gene, or autosomal recessive Parkin, P-TEN-induced putative kinase 1 gene and Daisuke-Junko 1 gene, has provided great insights into the pathogenesis of Parkinson's disease (PD).
