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(More)
The Parkinson's disease (PD) causative PINK1 gene encodes a mitochondrial protein kinase called PTEN-induced kinase 1 (PINK1). The autosomal recessive pattern of inheritance of PINK1 mutations suggests that PINK1 is neuroprotective and therefore loss of PINK1 function causes PD. Indeed, overexpression of PINK1 protects neuroblastoma cells from undergoing(More)
Mutations of the phosphatase and tensin homolog (PTEN)-induced kinase 1 (PINK1) gene can cause early-onset familial Parkinson disease (PD). PINK1 encodes a neuroprotective protein kinase localized at the mitochondria, and its involvement in regulating mitochondrial dynamics, trafficking, structure, and function is well documented. Owing to the lack of(More)
