WebJan 1, 2012 · In the cytoplasm Nrf2 is bound to kelch-like ECH-associated protein 1 (Keap1), which prohibits Nrf2 nuclear translocation and thus facilitates constant proteasomal degradation. Upon oxidative stress, dissociation of Nrf2 from Keap1 permits Nrf2 shuttling into the nucleus, ... 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) .
WebMar 24, 2024 · In the cytoplasm, Keap1, the main regulator of Nrf2, is a substrate adaptor protein for the Cul3-Keap1-E3 ligase complex that ubiquinates Nrf2, marking it for proteasomal degradation in the cytoplasm under basal conditions ( Baird and Yamamoto, 2024; Dayalan Naidu and Dinkova-Kostova, 2024 ). WebApr 18, 2002 · Nrf2, a regulator of inflammation in wounded skin. To elucidate the function of Nrf2 in the wound healing process, we wounded Nrf2 knockout mice. The results …
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… WebSep 2, 2024 · Nrf2 is localized in the cytoplasm under steady-state conditions and is isolated by its inhibitor KEAP1 . There is controversy regarding the role of Nrf2 in cancer, …
WebApr 9, 2024 · Under normal conditions, Nrf2 is in a complex with the inhibitory proteins Keap1 via the ETBE and DLG domains. Keap1 proteins enable the ubiquitination of the Nrf2 protein and, subsequently, its degradation in the proteasome. Keap1 proteins represent a regulatory mechanism by which the amount of Nrf2 in the cell’s cytoplasm is regulated.
