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

PNAS：遗传改造Parkin蛋白可减缓果蝇衰老
一项研究发现，被遗传改造成产生大量的细胞蛋白Parkin蛋白的果蝇比没有经过改造的果蝇寿命长了28%。 近日，加州大学洛杉矶分校的科学家培育出了可以诱导产生过量的Parkin蛋白的果蝇，这种蛋白涉及了某些类型的帕金森疾病以及被认为是与衰老有关的其他分子机制。 当研究人员增加成年果蝇在
泛素化酶USP33调控PINK1Parkin介导的线粒体自噬过程
PINK1-Parkin介导的线粒体自噬在线粒体质量控制过程中发挥着关键作用，其调控异常与人类神经退行性疾病发生相关。已有研究表明Parkin蛋白泛素化和去泛素化修饰参与线粒体自噬调控过程，但Parkin蛋白的去泛素化酶及其调控线粒体自噬的分子机制尚不清楚。在线粒体解偶联剂CCCP处理下，去泛素
