  • a potential catalytic triad (S32, H26, D140) from the crystal structure, that can plays an essential role for interactions of Prdx6 with phospholipid substrate to optimize the protein-substrate complex for hydrolysis

  • thiol-specific antioxidant protein family
  • Rehydrin subfamily
  • CATEGORY enzyme , regulatory
    SUBCELLULAR LOCALIZATION     intracellular
  • localization in acidic organelles and consequent PLA2 activity depend on a novel 10-AAs peptide located at positions 31-40 of the protein
  • localized mainly in the nucleus of neural cells
  • basic FUNCTION
  • "moonlighting" protein with both GSH peroxidase and phospholipase A2 (PLA2)) activities
  • involved in redox regulation of the cell
  • reducing H(2)O(2) and short chain organic, fatty acid and phospholipid hydroperoxides
  • playing a role in the regulation of phospholipid turnover as well as in protection against oxidative injury
  • regulating, with arachidonic acid, striated muscle growth by modulating multiple growth-regulatory pathways
  • bifunctional enzyme with two distinct active sites
  • required for blood vessel integrity in wounded skin
  • important antioxidant enzyme in human brain defenses
  • attenuates oxidative stress- and TGFbeta-induced abnormalities of trabecular meshwork cells
  • binds to reduced phospholipid at acidic pH but at cytosolic pH binds only phospholipid that is oxidized compatible with a role in the repair of peroxidized cell membranes
  • in uterus PRDX6 also plays antioxidant roles in human implantation
    metabolism lipid/lipoprotein
  • phospholipd and lipid catabolism
  • FKBP4PRDX6 signaling protects pregnancy from overt oxidative stress
  • a component
    small molecule
  • direct interaction between SFTPA1, which provides a mechanism for regulation of the PLA(2) activity of PRDX6 by SFTPA1
  • physical interaction between FKBP4 and PRDX6 suggests that FKBP4 stabilizes PRDX6 protein and attenuates its degradation as a function of its chaperone activity
  • cell & other
    inhibited by irreversibly inactivated by overoxidation of Cys-46 (to CYS-SO3H) upon oxidative stress
