NRF2 is kept in the cytoplasm by Kelch like-ECH-associated protein 1 and Cullin 3, which degrade NRF2 by ubiquitination. [19] Cullin 3 ubiquitinates NRF2, while Keap1 is a substrate adaptor protein that facilitates the reaction. Once NRF2 is ubiquitinated, it is transported to the proteasome, where it is degraded and its components recycled.
In molecular biology and genetics, transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA (transcription), thereby orchestrating gene activity. A single gene can be regulated in a range of ways, from altering the number of copies of RNA that are transcribed, to the temporal control of when the gene is ...
A series of synthetic oleane triterpenoid compounds, known as antioxidant inflammation modulators (AIMs), are being developed by Reata Pharmaceuticals, Inc. and are potent inducers of the Keap1-Nrf2 pathway, blocking Keap1-dependent Nrf2 ubiquitination and leading to the stabilization and nuclear translocation of Nrf2 and subsequent induction ...
transcriptional regulation – controlling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA; upregulation, activation, or promotion – increase the rate of gene transcription; downregulation, repression, or suppression – decrease the rate of gene transcription

Nuclear respiratory factor 1, also known as Nrf1, Nrf-1, NRF1 and NRF-1, encodes a protein that homodimerizes and functions as a transcription factor which activates the expression of some key metabolic genes regulating cellular growth and nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and replication.
