[[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 multifunctional protein that plays essential roles in tissues with higher order biological functions such as the testis and brain. DJ-1 is related to male fertility, and its level in sperm decreases in response to exposure to sperm toxicants. DJ-1 has also been identified as a hydroperoxide-responsive protein. Recently, a mutation of DJ-1 was found to be responsible for familial Parkinson's disease. Here, we present the crystal structure of DJ-1 refined to 1.95-A resolution. DJ-1 forms a dimer in the crystal, and the monomer takes a flavodoxin-like Rossmann-fold. DJ-1 is structurally most similar to the monomer subunit of protease I, the intracellular cysteine protease from Pyrococcus horikoshii, and belongs to the Class I glutamine amidotransferase-like superfamily. However, DJ-1 contains an additional alpha-helix at the C-terminal region, which blocks the putative catalytic site of DJ-1 and appears to regulate the enzymatic activity. DJ-1 may induce conformational changes to acquire catalytic activity in response to oxidative stress.
