背景信息

Peroxiredoxin 5 (PRDX5) is a multifunctional antioxidant enzyme belonging to the peroxiredoxin family, which plays a critical role in cellular redox homeostasis. It is ubiquitously expressed in various tissues and localized in multiple subcellular compartments, including mitochondria, cytoplasm, peroxisomes, and the nucleus. PRDX5 primarily functions to detoxify reactive oxygen species (ROS), such as hydrogen peroxide (H₂O₂) and peroxynitrite (ONOO⁻), through its conserved catalytic cysteine residues. Unlike other peroxiredoxins, PRDX5 exhibits a unique structural and mechanistic flexibility, enabling it to interact with diverse substrates and participate in redox signaling pathways beyond mere antioxidant defense.

Recombinant PRDX5 protein is produced using genetic engineering techniques, typically expressed in bacterial (e.g., *E. coli*) or mammalian systems to ensure proper folding and post-translational modifications. The recombinant form retains the enzymatic activity of native PRDX5. making it a valuable tool for studying oxidative stress-related mechanisms. Its applications span in vitro assays, cell culture studies, and animal models to investigate conditions like neurodegenerative diseases, cancer, diabetes, and inflammatory disorders. Additionally, recombinant PRDX5 has therapeutic potential, with research exploring its use in mitigating oxidative damage or enhancing cellular resilience. Recent studies also highlight its role in modulating immune responses and apoptosis, further underscoring its biological significance. The production of recombinant PRDX5 enables standardized research into its structure-function relationships, substrate specificity, and interactions with partner proteins, advancing both basic science and drug development efforts.
