WebJul 29, 2024 · Dissociation of Keap1 and Cul3 hinders Nrf2 ubiquitination, and finally, Nrf2 stabilizes freely in the cytoplasm . Autophagy-dysregulation and Nrf2 P62 protein (or sequestosome 1 [SQSTM1]) is an essential regulator of Nrf2, which acts in a Keap1-dependent manner through a non-canonical pathway of NF-κB [ 44 , 45 ]. WebMay 2, 2024 · In the cytoplasm, NRF2 is ubiquitinated by the KEAP1-CUL3 ubiquitin E3 ligase complex to mark it for degradation by the proteasome.
