WebApr 1, 2024 · Nrf2 affects transcription by binding to the antioxidant response element (ARE) in the promoter regions of its target genes [ 15, 16 ]. We previously demonstrated that at least some of the Nrf2-activated genes are also activated by MICs [ 7, 8, 17 ]. NFE2L2 and other genes, such as NFE2, NFE2L1 and NFE2L3, encode basic leucine zipper (bZIP) transcription factors. They share highly conserved regions that are distinct from other bZIP families, such as JUN and FOS, although remaining regions have diverged considerably from each other. Under normal or unstressed conditions, NRF2 is kept in the cytoplasm by a cl…
