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. WebNormally, a concentration of free Nrf2 in cytoplasm is low, as it is predominantly in the complex with Keap1 repressor protein, which leads to Nrf2 proteasomal degradation. …

The transfection was performed using Lipofectamine 2000, and cells were transfected for 48 h at 37°C. The transfection efficiency was confirmed by Western blotting.
WebSep 23, 2024 · In the cytoplasm, Nrf2 is bound to its partner, Keap1, and is rapidly degraded through the ubiquitin–proteasome pathway (Zheng et al. 2024a). It has been demonstrated that p62 directly interacts with Keap1, thereby dissociating it from Nrf2 and directing it toward autophagic degradation (Deng et al. 2024 ; Dodson et al. 2015 ).
