**Background of NFE2L2 Recombinant Protein**
NFE2L2 (Nuclear Factor Erythroid 2-Related Factor 2), also known as Nrf2. is a transcription factor central to cellular defense mechanisms against oxidative stress and xenobiotic damage. It regulates the expression of antioxidant response element (ARE)-driven genes, which encode detoxifying enzymes (e.g., NAD(P)H quinone oxidoreductase 1), antioxidant proteins (e.g., heme oxygenase-1), and drug transporters. Under basal conditions, NFE2L2 is sequestered in the cytoplasm by its inhibitor, KEAP1. and targeted for proteasomal degradation. Upon exposure to oxidative stress or electrophilic agents, KEAP1-mediated degradation is disrupted, allowing NFE2L2 to translocate to the nucleus, dimerize with small Maf proteins, and activate cytoprotective gene transcription.
Recombinant NFE2L2 protein is engineered for research and therapeutic applications, typically produced in *E. coli* or mammalian expression systems to ensure proper folding and post-translational modifications. Its structure includes conserved domains critical for function: the Neh2 domain (KEAP1 interaction), Neh4/5 domains (transactivation), and the CNC-bZIP domain (DNA binding).
Studies leveraging recombinant NFE2L2 focus on elucidating its regulatory mechanisms, screening small-molecule activators (e.g., sulforaphane, omaveloxolone), and modeling diseases linked to oxidative stress, such as cancer, neurodegenerative disorders (e.g., Alzheimer’s), and chronic inflammation. Dysregulation of NFE2L2 is implicated in both pathological oxidative damage (via loss of function) and cancer progression (via hyperactivation in some contexts). Therapeutic strategies aim to modulate NFE2L2 activity, either by enhancing its cytoprotective role or suppressing its oncogenic effects. Recombinant NFE2L2 thus serves as a vital tool for drug discovery and mechanistic studies in redox biology.
