  • a signal peptide
  • two peroxide catalysis cysteine motifs conserved in all peroxiredoxins
  • mono polymer homomer , heteromer , dimer
    FAMILY peroxiredoxin family
    CATEGORY enzyme
    intracellular,cytoplasm,organelle,endoplasmic reticulum
  • localized mainly in the nucleus of neural cells
  • only endoplasmic reticulum localized peroxiredoxin
  • basic FUNCTION
  • playing a regulatory role in the activation of the transcription factor NF-kappaB
  • involved in protection against oxidative stress through the detoxification of cellular peroxides
  • endoplasmic reticulum-localized enzyme forming oligomeric complexes in human cells
  • important for spermatogenesis, but not an absolute requisite
  • essential for preventing respiratory syncytial virus-induced oxidative damage in a subset of nuclear intermediate filament and actin binding proteins in epithelial cells
  • ER-localized and implicated in a previously unanticipated, parallel, ERO1-independent pathway that couples hydroperoxide production to oxidative protein folding in mammalian cells
  • PRDX3 and PRDX4, may act as new placental immune targets, and are involved in recurrent pregnancy loss
  • different binding properties of ERO1A and PRDX4 increase the robustness of ER redox homeostasis
  • may have a close relationship with follicular development
  • PRDX4-recycling in the endoplasmic reticulum is much less efficient than in the cytosol or mitochondria, leading to the protection of PRDX4 from hyperoxidation
  • ER-specific antioxidative peroxidase that can utilize luminal H2O2 as driving force for reoxidizing protein disulfide isomerase family members, thus efficiently contributing to disulfide bond formation
  • important role of PRDX4 in maintaining insulin levels and improving the ER folding capacity also under conditions of a high insulin requirement
  • functions not only to eliminate peroxide but also to promote oxidative protein folding via oxidizing protein disulfide isomerase (PDI)
  • novel function of secreted PRDX4 in mediating osteoclast activation by cancer cells
  • PRDX4 oxidative activity acts as a sensor to directly couple neuronal differentiation with redox environments in the ER
  • PRDX2 and PRDX4 are negative regulators of hypoxia-inducible factors under conditions of prolonged hypoxia
    a component heterodimer with PRDX1; disulfide-linked, upon oxidation
    small molecule
  • NFKB (activation of NFKB)
  • ER-resident antioxidant PRDX4 interacts with the cytoplasmic domain of the granulocyte colony-stimulating factor receptor (CSF3)
  • PTPN1 might keep PRDX4 active by reducing its phosphorylation
  • TXNDC5 is involved in insulin production as well as in adiponectin signaling and interacts specifically with the redox-regulatory endoplasmic reticulum proteins ERO1A and PRDX4
  • PDIA2 binds preferentially ERO1A, whereas ERP44 equally retains ERO1A and PRDX4
  • GDPD5 is targeted by PRDX4 oxidative activity (PRDX4 dimers oxidize two cysteine residues within the GDPD5 enzymatic domain, which blocks GDPD5 trafficking to the plasma membrane and prevents GDPD5 neurogeneic function)
  • cell & other
    inhibited by TNFSF10 at the transcriptional level, and downregulation of PRDX4 might facilitate cell death induced by TNFSF10
