Recombinant Human PARK2 protein
Recombinant Human PARK2 was expressed in Insect cells.
The E3 Ubiquitin ligase Parkin (encoded by the PARK2 gene) is an essential part of the cellular machinery that participates in the removal of damaged mitochondria. Mutations in PARK2 are known to cause a form of Parkinson's disease known as autosomal recessive juvenile Parkinson's disease (AR-JP), and the mechanisms by which defective Parkin ligase contributes to the dopaminergic cell death in this disease is an area of intense investigation.

Reaction conditions will need to be optimized for each specific application. As supplied, Parkin has negligible E3 ligase activity as determined by the lack of autoubiquitination in an in vitro assay. Parkin ligase activity is greatly enhanced by phosphorylation with PINK1 kinase or by the addition of low concentrations of phosphorylated Ubiquitin.
