Nrf3 associates with small Maf proteins to bind the antioxidant response element (ARE) and acts as a negative regulator of ARE-mediated NQO1 gene expression; repression requires the heterodimerization and DNA-binding domains but not the transcriptional activation domain. RNAi knockdown of Nrf3 increases NQO1 expression, confirming endogenous repressive function. |

Nrf3 is targeted to the ER through its N-terminal NHB1 sequence, which functions as a tripartite signal peptide (n, h, c regions). The h region (residues 12–23) directs ER targeting and is required for Asn glycosylation; the c region (residues 24–39) contains a signal peptidase cleavage site generating the ~90-kDa mature glycoprotein from a ~96-kDa precursor. The ~90- and ~80-kDa isoforms localize to the nuclear envelope and the ~70-kDa (non-glycated) isoform to the nucleoplasm. ER stressors tunicamycin and brefeldin A activate Nrf3, and NHB1 is required for this response. |

Nrf3 is required for smooth muscle cell (SMC) differentiation from embryonic stem cells. Nrf3 overexpression dose-dependently enhances SMC differentiation and upregulates the SMC-specific transcription factor myocardin (but not SRF). Nrf3 directly binds to promoters of SMC differentiation genes (ChIP). Nrf3 overexpression enhances NADPH oxidase-dependent ROS production and inhibits antioxidant signaling, and Nrf3 is involved in ER stressor-induced SMC differentiation. |

Under basal conditions NRF3 is rapidly degraded in the cytoplasm by the ER-associated degradation (ERAD) ubiquitin ligase HRD1 and VCP (valosin-containing protein). Nuclear NRF3 is separately degraded by β-TRCP, an adaptor for the SCF ubiquitin ligase. Nuclear translocation of NRF3 from the ER requires the aspartic protease DDI2 but does not require inhibition of HRD1-VCP-mediated degradation. NRF3 induces expression of UHMK1 (U2AF homology motif kinase 1) to promote cell proliferation. |

NFE2L3 and NFE2L1 complementarily maintain basal proteasome activity in cancer cells. NFE2L3 represses NFE2L1 translation by inducing CPEB3, which binds the 3' UTR of NFE2L1 mRNA and reduces polysome formation on it. Double knockdown of NFE2L1 and NFE2L3 impairs basal proteasome activity and reduces expression of seven proteasome-related genes (PSMB3, PSMB7, PSMC2, PSMD3, PSMG2, PSMG3, POMP). |
