  • 功能：
    Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides and as sensor of hydrogen peroxide-mediated signaling events. Regulates the activation of NF-kappa-B in the cytosol by a modulation of I-kappa-B-alpha phosphorylation.
  • 基因功能参考文献：
    1. These features indicate that PRDX4 plays an important role in protecting against liver injury following BDL and might be a promising therapeutic modality for cholestatic diseases. PMID: 30149550
    2. Significant reduction in mRNA and protein levels of PrdxIV was observed in HEK293 cells overexpressing pathologically relevant recombinant mutant GNE protein (D207V and V603L) compared with vector control. Downregulation of PrdxIV keep the ER in a reduced (redox) state that may contribute to misfolding and aggregation of proteins in GNE myopathy. PMID: 28895049
    3. levels of peroxiredoxin 4 are higher in patients with prediabetes, but are similar in subjects with and without insulin resistance, which suggests that the main factor for its increased levels is hyperglycaemia and not insulin sensitivity state. PMID: 27303935
    4. Results show that ERp44 binds the oxidized but not the reduced form of Prx4; the ERp44-Prx4 complex is formed via thiol-disulfide interchange reactions, and its crystal structure reveals a redox-dependent recognition. PMID: 27642162
    5. Prdx4 expression was closely related to follicular development and has aprominent role in protecting human and mouse granulosa cells from reactive oxygen species damage. PMID: 26917265

    14. peroxiredoxin IV recycling in the endoplasmic reticulum is much less efficient than in the cytosol or mitochondria, leading to the protection of peroxiredoxin IV from hyperoxidation. PMID: 24403061
    15. Remarkably, the Prx4-dependent formation of native disulfide bonds was accelerated when PDI was combined with ERp46 or P5, suggesting that PDIs work synergistically to increase the rate and fidelity of oxidative protein folding. PMID: 23949117
    16. Data indicate that protein disulfide isomerase (PDI) and ERp44 dynamically localize Ero1alpha and peroxiredoxin 4 in early secretory compartment (ESC). PMID: 23979138
    17. expression of Prxs I and IV, both at mRNA and protein levels, was associated with light chain secretion quantified by ELISA. PMID: 23737084
