NFE2L2 Protein, Human (sf9, GST)

NFE2L2 is a pivotal transcription factor that plays a central role in cellular response to oxidative stress. NFE2L2 binds to the antioxidant response elements in the promoter regions of various cytoprotective genes. NFE2L2 is ubiquitinated and degraded by the BCR(KEAP1) complex in the cytoplasm under normal physiological conditions. NFE2L2 accumulates in the nucleus when electrophilic metabolites inhibit the BCR(KEAP1) complex during oxidative stress, then forms heterodimers with small Maf proteins and combines with antioxidant response elements of cytoprotective target genes. NFE2L2 can also be activated by selective autophagy, as autophagy enhances the interaction between KEAP1 and SQSTM1/p62 to inactivate the BCR(KEAP1) complex and facilitate its nuclear accumulation. NFE2L2 contributes to the transcriptional activation of genes in the β-globin cluster beyond regulating oxidative stress. NFE2L2 acts as a key regulator of innate immunity and antiviral cytoplasmic DNA sensing, and modulates redox homeostasis and aberrant pro-inflammatory signaling during sepsis. NFE2L2 suppresses inflammatory responses in macrophages and restrains the transcription and induction of pro-inflammatory cytokines such as IL6. NFE2L2 inhibits the expression of adaptor STING1 to block antiviral cytoplasmic DNA sensing and reduce the release of pro-inflammatory cytokines triggered by SARS-CoV-2 and other pathogenic viruses. NFE2L2 can be activated by cell-derived metabolites such as itaconic acid and fumaric acid^[1][2][3][4].
