General description

Nuclear factor erythroid 2-related factor 1 (NFE2-related factor 1/Nrf1), also known as NF-E2-related factor 1, NFE2-related factor 1, Nuclear factor erythroid derived 2 like 1, and encoded by the gene name Nfe2l1 and Nrf1, is a member of the bZIP family and the CNC subfamily. Isoform 3 of Nrf1 interacts with the extended kappa 3 site of the TNF alpha promoter after Fc gamma RIII stimulation and participates in the induction of this cytokine. Studies have suggested that isoform 1 of Nrf1 is either inactive or represses the transcriptional activation. Isoform 2 of Nrf1 has been shown to activate the expression of antioxidant response element (ARE) containing reporters and genes in cells, and may play a role in oxidative stress response. Other studies have suggested that isoform 1 also activates ARE-driven genes. Levels of Nrf1 isoform 2 in white fat, lung and liver are increased compared to isoform 1 (at protein level). Isoform 1 and isoform 2 of Nrf1 are widely expressed including kidney, brown fat, white fat, large intestine, small intestine, stomach, lung, brain and liver. Isoform 2 levels are elevated in brown fat and brain, but are reduced in liver compared to isoform 1 levels. Isoform 1 and isoform 2 are also expressed in mouse embryonic fibroblasts (MEF).
