Nrf2 is a transcription factor which belongs to the Cap N Collar (CNC-bZIP) subfamily with an implication in adaptive responses to oxidative stress. Nrf2 is a basic leucine zipper transcription factor that can bind to a NF-E2/AP-1 repeat sequence in the promoter of the beta-globin gene and has two types of binding partners, a cytoplasmic repressor (Keap I) and multiple nuclear binding partners. During oxidative stress on a cell, Nrf2 is released from Keap I, possibly via PKC phosphorylation at serine 40, and translocates to the nucleus. In the nucleus, Nrf2 binds to antioxidant responsive element (ARE) and leads to transcriptional activation of downstream genes for GSTs, glutamate-cysteine ligase, HO-1, and thioredoxin. Nrf2 and its downstream proteins have shown to have important functions in protection against oxidative stress or chemical-induced cellular damage in liver and lung, prevention in cancer formation in GI tract, and promotion of the wound-healing process. Post-translational: Ubiquitinated in the cytoplasm by the BCR(KEAP1) E3 ubiquitin ligase complex leading to its degradation (PubMed:15601839, PubMed:15983046, PubMed:19489739). In response to oxidative stress, electrophile metabolites, such as sulforaphane, modify KEAP1, leading to inhibit activity of the BCR(KEAP1) complex, promoting NFE2L2/NRF2 nuclear accumulation and activity (PubMed:19489739, PubMed:29590092). In response to autophagy, the BCR(KEAP1) complex is inactivated (By similarity). Phosphorylated by EIF2AK3/PERK following unfolded protein response (UPR), promoting dissociation from its cytoplasmic inhibitor KEAP1, followed by its translocation into the nucleus (By similarity). Phosphorylation of Ser-40 by PKC in response to oxidative stress dissociates NFE2L2 from its cytoplasmic inhibitor KEAP1, promoting its translocation into the nucleus (By similarity). Acetylation at Lys-596 and Lys-599 increases nuclear localization whereas deacetylation by SIRT1 enhances cytoplasmic presence. Glycation impairs transcription factor activity by preventing heterodimerization with small Maf proteins (PubMed:31398338). Deglycation by FN3K restores activity (PubMed:31398338).
