RoleofParkinintheUbiquitinProteasomalPathway
The motor defects of Parkinson's disease are related to the loss of dopaminergic neurons in specific brain regions. Examination of these neurons in diseased tissue has revealed the presence of Lewy bodies, dense aggregates that include the protein alpha-synuclein. A genetic basis for most cases of Parkinson's disease has not yet been identified, but mutations in alpha-synuclein have been associated with at le......阅读全文
