The distinction between graduate school and professional school is somewhat like the distinction between basic science and applied science; the differences lie in the focus. In graduate school, students focus primarily on mastering a particular field of study.
Protein deglycase DJ-1, also known as Parkinson disease protein 7, is a protein which in humans is encoded by the PARK7 gene.ARK7 belongs to the peptidase C56 family of proteins. The protein structures of human protein DJ-1, Escherichia coli chaperone Hsp31 and an Archaea protease are evolutionarily conserved.
Summary. The precise function of this gene is unknown; however, the encoded protein is a component of a multiprotein E3 ubiquitin ligase complex that mediates the targeting of substrate proteins for proteasomal degradation. PPI screens for parkin, a hereditary Parkinson's disease gene, elucidated the function of parkin as an E3 ubiquitin ligase, with localization regulated by contact with interaction partners, uncovering part of the pathogenesis of Parkinson's disease.
