Description

NFE2L2, commonly known as NRF2, serves as a master regulator of the cellular antioxidant response, orchestrating the expression of cytoprotective genes that defend against oxidative stress and electrophilic damage. This transcription factor plays a central role in maintaining cellular redox homeostasis and has emerged as a critical focus in cardiovascular disease research, metabolic disorders, and studies of cellular stress responses. Understanding NRF2 dynamics—its nuclear translocation, activation, and regulation—provides essential insights into how cells adapt to environmental challenges.

This recombinant monoclonal antibody, clone 2D12, offers the reproducibility and consistency that demanding research protocols require. Because it is produced from a defined genetic sequence rather than traditional hybridoma methods, you can expect uniform performance across experiments and between lots, eliminating a common source of variability in longitudinal studies. The rabbit IgG format, generated against a synthetic peptide derived from human NRF2, provides reliable detection in human samples.

Validation through immunofluorescence microscopy in HeLa cells demonstrates clear nuclear and cytoplasmic staining patterns at 1:50 dilution, with DAPI counterstaining confirming subcellular localization. This makes the antibody particularly well-suited for investigating NRF2 translocation events in response to oxidative stressors or pharmacological activators. The antibody is also validated for ELISA applications, with recommended IF dilutions ranging from 1:20 to 1:200, allowing flexibility in optimization for your specific experimental conditions.

Whether you are investigating epigenetic regulation of stress responses, exploring NRF2's role in cardiovascular protection, or characterizing metabolic pathway interactions, this antibody provides a dependable tool for advancing your research into this essential cellular defense pathway.

Target Background

Function

Transcription factor that plays a key role in the response to oxidative stress: binds to antioxidant response (ARE) elements present in the promoter region of many cytoprotective genes, such as phase 2 detoxifying enzymes, and promotes their expression, thereby neutralizing reactive electrophiles. In normal conditions, ubiquitinated and degraded in the cytoplasm by the BCR(KEAP1) complex. In response to oxidative stress, electrophile metabolites inhibit activity of the BCR(KEAP1) complex, promoting nuclear accumulation of NFE2L2/NRF2, heterodimerization with one of the small Maf proteins and binding to ARE elements of cytoprotective target genes. The NFE2L2/NRF2 pathway is also activated in response to selective autophagy: autophagy promotes interaction between KEAP1 and SQSTM1/p62 and subsequent inactivation of the BCR(KEAP1) complex, leading to NFE2L2/NRF2 nuclear accumulation and expression of cytoprotective genes. May also be involved in the transcriptional activation of genes of the beta-globin cluster by mediating enhancer activity of hypersensitive site 2 of the beta-globin locus control region. Plays also an important role in the regulation of the innate immune response and antiviral cytosolic DNA sensing. It is a critical regulator of the innate immune response and survival during sepsis by maintaining redox homeostasis and restraint of the dysregulation of proinflammatory signaling pathways like MyD88-dependent and -independent and TNF-alpha signaling. Suppresses macrophage inflammatory response by blocking proinflammatory cytokine transcription and the induction of IL6. Binds to the proximity of proinflammatory genes in macrophages and inhibits RNA Pol II recruitment. The inhibition is independent of the NRF2-binding motif and reactive oxygen species level. Represses antiviral cytosolic DNA sensing by suppressing the expression of the adapter protein STING1 and decreasing responsiveness to STING1 agonists while increasing susceptibility to infection with DNA viruses. Once activated, limits the release of pro-inflammatory cytokines in response to human coronavirus SARS-CoV-2 infection and to virus-derived ligands through a mechanism that involves inhibition of IRF3 dimerization. Also inhibits both SARS-CoV-2 replication, as well as the replication of several other pathogenic viruses including Herpes Simplex Virus-1 and-2, Vaccinia virus, and Zika virus through a type I interferon (IFN)-independent mechanism.
