Prdx5 regulates DNA damage response (DDR) through: (1) Plk1-mediated phosphorylation of ATM kinase activating downstream Chek1/Chek2; (2) increasing p53 acetylation at K382, stabilizing nuclear p53 and enhancing transcription; (3) induction of autophagy that regulates recycling of DDR molecules. Sirt2 was identified as a novel deacetylase of p53 at K382, acting in a Prdx5-dependent manner. |

IER3 interacts with the presenilin-associated rhomboid-like protein (PARL) and reduces its shear activity, thereby inhibiting cleavage and mitochondrial translocation of cytoplasmic PRDX5. Reduced mitochondrial PRDX5 impairs antioxidant capacity, causes oxidative mitochondrial damage, and promotes stress-induced cellular senescence driving AKI-to-CKD transition. |

Acetylation of PRDX5 inhibits its antioxidant and anti-apoptotic functions in retinal neurons under ischemia-reperfusion: OGD/R increases PRDX5 acetylation; increasing acetylation (NAM treatment) elevates ROS and apoptosis, while decreasing acetylation (NRC treatment) reduces ROS and apoptosis; inhibiting deacetylation abolishes the protective effect of PRDX5 overexpression. |

Under cryopreservation-induced oxidative stress, PRDX5 translocates intracellularly in bull sperm and forms high-molecular-weight oligomers detected by PAGE; oligomerization may shift PRDX5 function from peroxidase to chaperone. PRDX5 interaction with TLR4 may be key to its intracellular transport, and PRDX5 was detected in exosomal vesicles. |
