Peroxiredoxin 3 (PRDX3), a member of the peroxiredoxin family, is a mitochondrial antioxidant enzyme critical for regulating reactive oxygen species (ROS) and maintaining cellular redox homeostasis. As a thioredoxin-dependent peroxidase, it primarily localizes to the mitochondrial matrix, where it scavenges hydrogen peroxide (H₂O₂) and peroxynitrite generated during oxidative phosphorylation. PRDX3 plays a protective role against oxidative stress-induced damage to mitochondrial DNA, proteins, and lipids, thereby influencing apoptosis, metabolism, and cellular signaling pathways. Its dysfunction is linked to neurodegenerative diseases, cancer, aging, and metabolic disorders.
Recombinant PRDX3 protein is engineered using molecular cloning techniques, often expressed in bacterial (e.g., *E. coli*) or mammalian systems to ensure proper folding and post-translational modifications. This recombinant form retains enzymatic activity, enabling studies on mitochondrial oxidative stress mechanisms, drug screening, and therapeutic development. Structural analyses reveal its conserved thioredoxin-fold domain and catalytic cysteine residues essential for its peroxidase function. Researchers utilize recombinant PRDX3 to investigate its role in modulating ROS-related diseases, such as Parkinson’s disease, where mitochondrial oxidative damage is a hallmark. Additionally, it serves as a tool to explore PRDX3’s interactions with mitochondrial proteins or its potential as a biomarker. Studies also focus on its redox-sensitive signaling roles in inflammation and cancer progression. The recombinant protein’s stability and activity under varying oxidative conditions make it valuable for in vitro and in vivo models aiming to enhance antioxidant defenses or target mitochondrial dysfunction. Ongoing research explores its therapeutic potential, including gene therapy or small-molecule activators to boost PRDX3 expression in diseases characterized by mitochondrial oxidative stress.
