Final Report Abstract

Parkinson’s disease (PD) is associated with loss of dopaminergic cells and genetically linked to proteins that function in the management of cellular stress resulting from protein misfolding and oxidative damage. Mutations in the recently discovered PINK1 gene cause autosomal recessive PD. The main objective of this research study was to determine the molecular pathway of PINK1 and impact of mutated forms. We performed a mass spectroscopy analysis, using Stratagene’s Interplay Tandem Affinity Purification (TAP) system to identify novel interactors of PINK1. Several potential interactors have been identified, however confirmation studies are pending. Further, we could demonstrate that human skin fibroblasts containing mutated PINK1 display a mitochondrial dysfunction, with a p.V170G PINK1 mutation having an effect particularly on the respiratory chain.
