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… WebUnder normal conditions, Nrf2 is located in the cytoplasm and binds to Kelch-like ECHassociated protein (Keap1), which blocks Nrf2 from entering the nucleus (6)(7)(8).
WebDisruption of the Keap1–Nrf2 protein–protein interaction (PPI) was beneficial to release Nrf2, which stimulated Nrf2 translocating from cytoplasm to nucleus, binding to ARE, and then activating the antioxidative defense system to generate antioxidative enzymes such as heme oxygenase 1 (HO-1) and NADPH quinone oxidoreductase 1 (NQO1) .

WebApr 12, 2024 · Nevertheless, Zn deficiency inhibits the Nrf2 and MT4 expression both in the embryos and cells, aggravating the mitochondrial oxidative stress induced by BHP. It has been confirmed that Zn would act as an intracellular second messenger mediating the Nrf2 sensing of environmental stressors to activate MTs expressions in cells . Consistent with ...
WebDec 6, 2016 · In the normal hippocampus, Nrf2 is expressed in neurons and predominantly localised in the nucleus. In the AD brain, Nrf2 predominantly localises in the cytoplasm of hippocampal neurons and not a component of Aβ plaques or NFTs. Immunoblotting studies suggested that the Nrf2 levels were reduced in AD cases (Ramsey et al. 2007).
