Function

The protein expressed by the NFE2L2 gene functions as a transcription factor that plays a key role in responding to oxidative stress by binding to antioxidant response elements (ARE) in the promoter regions of various cytoprotective genes, such as phase 2 detoxifying enzymes, to promote their expression and neutralize reactive electrophiles. Under normal conditions, it is ubiquitinated and degraded in the cytoplasm by the BCR(KEAP1) complex. However, oxidative stress leads to the inhibition of the BCR(KEAP1) complex, allowing NFE2L2/NRF2 to accumulate in the nucleus, form heterodimers with small Maf proteins, and bind to ARE elements. Additionally, the NFE2L2/NRF2 pathway is activated by selective autophagy, where KEAP1 interacts with SQSTM1/p62, inactivating the BCR(KEAP1) complex and leading to nuclear NFE2L2/NRF2 accumulation and cytoprotective gene expression. It may also be involved in activating genes of the beta-globin cluster by facilitating enhancer activity of hypersensitive site 2 of the beta-globin locus control region. This supplementary information is collated from multiple sources and compiled automatically.

Representative findings of Nrf2 staining in carcinoma (left), in low grade dysplasia (middle), and in non-atypical epithelium (right).
Corresponding PLA signals are displayed in the lower row. Scale bar; 100 μm.
Surgical specimens were transferred to 10% buffered formalin and fixed overnight. The fixed samples were embedded in paraffin, and serially sliced into 5 μm sections. After dewaxing, sections were autoclaved at 120°C for 1 min in 10 mM sodium citrate buffer (pH 6.0), and immersed in 0.3% H₂O₂. They were then incubated overnight at 4°C with primary antibody to Nrf2 (diluted 1:200). The sections were rinsed with 1×PBS and incubated with the secondary antibody conjugated with horseradish peroxidase at room temperature for 1 hour. The sections were then stained with 3.3′-diaminobenzidinetetrahydrochloride (DAB) and counterstained with hematoxylin.
