  • basic FUNCTION
  • functioning as a positive regulator of androgen receptor
  • involved in the oxidative stress response
  • protecting against mitochondrial damage and may be protecting neurons from various stressful stimuli
  • neuroprotective transcriptional co-activator that may act in concert with NONO and SFPQ to regulate the expression of a neuroprotective genetic program
  • having a functional role in scavenging mitochondrial H2O2 because of its physiological action as an atypical peroxiredoxin-like peroxidase
  • multi-functional protein that plays roles in transcriptional regulation and anti-oxidative stress function
  • involved in cancer by promoting Ras signaling and suppressing PTEN-induced apoptosis
  • may play roles in coordinating responses to oxidative damage and suppression of cell death
  • protect cells against hypoxia-induced cell death and is required for their adaptation to severe hypoxic stress
  • degrades aggregated TTR to protect against the onset of FAP (familial amyloidotic polyneuropathy)
  • upstream activator of HIF1 function in cancer cells and its oncogenic activity stems from its ability to increase a cell resistance to hypoxic stress
  • plays roles in transcriptional regulation and anti-oxidative stress
  • integral mitochondrial protein that plays a role in maintenance of mitochondrial complex I activity
  • crucial for full activation of AKT1 upon oxidative injury, which serves as one explanation for the protective effects of PARK7
  • exerts an important role in the regulation of the AKT1 pathway in response to oxidative stress and neuronal protection
  • important for proper mitochondrial function and acts downstream of, or in parallel to, PINK1
  • is in a pathway parallel to that of PINK1/parkin and both of these pathways, and their carefully balanced activity, are critical for mitochondrial function
  • works in parallel to the PINK1/parkin pathway to maintain mitochondrial function in the presence of an oxidative environment
  • influences mitochondrial function and morphology through an oxidative stress pathway
  • function may either contribute to the regulation of autophagy or mitigate the downstream effects of ROS
  • antioxidant function of PARK7 by increasing TXN expression via NFE2L2-mediated transcriptional induction
  • multifunctional protein that acts as an antioxidant and a transcriptional regulator
  • cytoprotective activity of PARK7 is mediated by the transcriptional induction of the TXN gene through the NFE2L2 pathway
  • serves as scavengers for reactive carbonyl species may provide a new insight into the causation of Parkinson disease
  • converting glyoxal or methylglyoxal to glycolic or lactic acid, respectively, in the absence of glutathione
  • is closely associated with the differentiation of neural stem cells
  • stimulates the differentiation of human mesenchymal stem cells to osteoblasts and induces angiogenesis in endothelial cells through activation of FGFR1 signalling
  • regulates retinal pigment epithelium (RPE) responses to oxidative stress
  • function in lipid rafts, which may contribute the pathogenesis of Parkinson disease
  • may be implicated in the regulation of vascular contractility and blood pressure
  • function as an antioxidant, redox-sensitive molecular chaperone, and transcription regulator, which protected cells from oxidative stress by modifying signaling pathways that regulate cell survival
  • PARK7 and consequently its products are components of a novel pathway that stabilizes mitochondria during cellular stress
  • exerts its antioxidant activities, at least partly through regulation of PON2
    a component

  • interacting with PARK2 and PINK1 (PARK7, PINK1, and PARK2 function in common biological processes that are critical for mitochondrial function, such that compromise of their activity leads to human disease)
  • novel species-specific transcriptional regulation of the TH promoter by PARK7
  • PARK7 controls cell survival and possibly tumor progression via interaction with OTUD7B
  • PARK7 protects cells against UVB-induced cell death dependent on its oxidation and its association with mitochondrial BCL2L1
  • PARK7 stimulates SLC18A2 activity in the synapse by transactivation of the SLC18A2 gene and by direct binding to SLC18A2 and cysteine 106 is necessary for the stimulating activity of PARK7 toward SLC18A2
  • FIS1 degradation by PARK7 signalling in the regulation of oxidative stress-induced neuronal cell death supplies a novel mechanism of PARK7 in neuronal protection
  • directly bound to PYCR1 (both colocalized in mitochondria, and were suggested to be involved in regulation of mitochondrial membrane potential, but differently)
  • induces the expression of thioredoxin (TXN)
  • PARK7 interacts with GNB2L1 and increases its dimerization and protein stability
