== Disease ==
[[http://www.uniprot.org/uniprot/PARK7_HUMAN PARK7_HUMAN]] Defects in PARK7 are the cause of Parkinson disease type 7 (PARK7) [MIM:[http://omim.org/entry/606324 606324]]. A neurodegenerative disorder characterized by resting tremor, postural tremor, bradykinesia, muscular rigidity, anxiety and psychotic episodes. PARK7 has onset before 40 years, slow progression and initial good response to levodopa. Some patients may show traits reminiscent of amyotrophic lateral sclerosis-parkinsonism/dementia complex (Guam disease).<ref>PMID:12851414</ref> <ref>PMID:12446870</ref> <ref>PMID:14713311</ref> <ref>PMID:12953260</ref> <ref>PMID:15365989</ref> <ref>PMID:14607841</ref> <ref>PMID:15254937</ref> <ref>PMID:17846173</ref>  
== Function ==
[[http://www.uniprot.org/uniprot/PARK7_HUMAN PARK7_HUMAN]] Protects cells against oxidative stress and cell death. Plays a role in regulating expression or stability of the mitochondrial uncoupling proteins SLC25A14 and SLC25A27 in dopaminergic neurons of the substantia nigra pars compacta and attenuates the oxidative stress induced by calcium entry into the neurons via L-type channels during pacemaking. Eliminates hydrogen peroxide and protects cells against hydrogen peroxide-induced cell death. May act as an atypical peroxiredoxin-like peroxidase that scavenges hydrogen peroxide. Following removal of a C-terminal peptide, displays protease activity and enhanced cytoprotective action against oxidative stress-induced apoptosis. Stabilizes NFE2L2 by preventing its association with KEAP1 and its subsequent ubiquitination. Binds to OTUD7B and inhibits its deubiquitinating activity. Enhances RELA nuclear translocation. Binds to a number of mRNAs containing multiple copies of GG or CC motifs and partially inhibits their translation but dissociates following oxidative stress. Required for correct mitochondrial morphology and function and for autophagy of dysfunctional mitochondria. Regulates astrocyte inflammatory responses. Acts as a positive regulator of androgen receptor-dependent transcription. Prevents aggregation of SNCA. Plays a role in fertilization. Has no proteolytic activity. Has cell-growth promoting activity and transforming activity. May function as a redox-sensitive chaperone.<ref>PMID:9070310</ref> <ref>PMID:11477070</ref> <ref>PMID:12612053</ref> <ref>PMID:14749723</ref> <ref>PMID:15502874</ref> <ref>PMID:15976810</ref> <ref>PMID:16390825</ref> <ref>PMID:17015834</ref> <ref>PMID:18626009</ref> <ref>PMID:18711745</ref> <ref>PMID:20304780</ref> <ref>PMID:21097510</ref> <ref>PMID:12939276</ref> <ref>PMID:15181200</ref>

== Publication Abstract from PubMed ==
DJ-1 is a Parkinson's disease associated protein endowed with enzymatic, redox sensing, regulatory, chaperoning, and neuroprotective activities. Although DJ-1 has been vigorously studied for the past decade and a half, its exact role in the progression of the disease remains uncertain. In addition, little is known about the spatiotemporal regulation of DJ-1, or the biochemical basis explaining its numerous biological functions. Progress has been hampered by the lack of inhibitors with precisely known mechanisms of action. Herein, we have employed biophysical methodologies and X-ray crystallography to identify and to optimize a family of compounds inactivating the critical Cys106 residue of human DJ-1. We demonstrate these compounds are potent inhibitors of various activities of DJ-1 in vitro and in cell-based assays. This study reports a new family of DJ-1 inhibitors with a defined mechanism of action, and contributes toward the understanding of the biological function of DJ-1.
