Abstract

Mutations in PTEN-induced kinase 1 (PINK1) gene cause PARK6 familial Parkinsonism. To decipher the role of PINK1 in pathogenesis of Parkinson's disease (PD), researchers need to identify protein substrates of PINK1 kinase activity that govern neuronal survival, and establish whether aberrant regulation and inactivation of PINK1 contribute to both familial Parkinsonism and idiopathic PD. These studies should take into account the several unique structural and functional features of PINK1. First PINK1 is a rare example of a protein kinase with a predicted mitochondrial-targeting sequence and a possible resident mitochondrial function. Second, bioinformatic analysis reveals unique insert region..
