Recombinant human OXR1 (Oxidation Resistance 1) protein is a key regulator in cellular defense mechanisms against oxidative stress, a critical process implicated in aging, neurodegeneration, and various diseases. The OXR1 gene was first identified for its role in protecting DNA and biomolecules from reactive oxygen species (ROS)-induced damage. Structurally, OXR1 contains conserved TBC (Tre-2/Bub2/Cdc16) and GRAM (Glucosyltransferases, Rab-like GTPase activators, Myotubularins) domains, which mediate its interactions with signaling pathways and organelles. Studies highlight its localization in the cytoplasm and mitochondria, where it modulates antioxidant response systems, including the stabilization of antioxidant enzymes and regulation of mitochondrial function.
OXR1 is particularly vital in neuronal survival; its deficiency is linked to neurodegenerative disorders like Alzheimer’s and Parkinson’s diseases. Preclinical models show that OXR1 overexpression mitigates oxidative neuronal injury and enhances stress resilience. Recombinant OXR1 protein, produced via heterologous expression systems, enables researchers to explore its therapeutic potential, mechanisms in ROS scavenging, and crosstalk with pathways like Nrf2 and mTOR. Current research focuses on leveraging recombinant OXR1 to develop neuroprotective therapies or biomarkers for oxidative stress-related conditions, underscoring its dual role as a molecular safeguard and a target for drug discovery.
