Endoplasmic reticulum membrane sensor that translocates into the nucleus in response to various stresses to act as a transcription factor (PubMed:20385086, PubMed:21536885, PubMed:23816881, PubMed:29149604). Constitutes a precursor of the transcription factor NRF1. Able to detect various cellular stresses, such as cholesterol excess, oxidative stress or proteasome inhibition (PubMed:20385086, PubMed:21536885, PubMed:23816881, PubMed:29149604). In response to stress, it is released from the endoplasmic reticulum membrane following cleavage by the protease DDI2 and translocates into the nucleus to form the transcription factor NRF1 (PubMed:29149604). Acts as a key sensor of cholesterol excess: in excess cholesterol conditions, the endoplasmic reticulum membrane form of the protein directly binds cholesterol via its CRAC motif, preventing cleavage and release of the transcription factor NRF1, thereby allowing expression of genes promoting cholesterol removal, such as CD36 (PubMed:29149604). Involved in proteasome homeostasis: in response to proteasome inhibition, it is released from the endoplasmic reticulum membrane, translocates to the nucleus and activates expression of genes encoding proteasome subunits (PubMed:20385086, PubMed:21536885, PubMed:23816881).4 Publications
CNC-type bZIP family transcription factor that translocates to the nucleus and regulates expression of target genes in response to various stresses (PubMed:10601325, PubMed:11342101, PubMed:23144760, PubMed:16872277, PubMed:21911472, PubMed:23816881, PubMed:29149604). Heterodimerizes with small-Maf proteins (MAFF, MAFG or MAFK) and binds DNA motifs including the antioxidant response elements (AREs), which regulate expression of genes involved in oxidative stress response (PubMed:12808106, PubMed:15738389, PubMed:23144760, PubMed:16872277, PubMed:21911472, PubMed:23816881). Activates or represses expression of target genes, depending on the context (PubMed:12808106, PubMed:15738389, PubMed:23144760, PubMed:16872277, PubMed:21911472, PubMed:23816881). Plays a key role in cholesterol homeostasis by acting as a sensor of cholesterol excess: in low cholesterol conditions, translocates into the nucleus and represses expression of genes involved in defense against cholesterol excess, such as CD36 (PubMed:29149604). In excess cholesterol conditions, the endoplasmic reticulum membrane form of the protein directly binds cholesterol via its CRAC motif, preventing cleavage and release of the transcription factor NRF1, thereby allowing expression of genes promoting cholesterol removal (PubMed:29149604). Critical for redox balance in response to oxidative stress: acts by binding the AREs motifs on promoters and mediating activation of oxidative stress response genes, such as GCLC, GCLM, GSS, MT1 and MT2 (PubMed:10601325, PubMed:11342101, PubMed:12968018, PubMed:15738389, PubMed:18826952). Plays an essential role during fetal liver hematopoiesis: probably has a protective function against oxidative stress and is involved in lipid homeostasis in the liver (PubMed:9501099, PubMed:12808106, PubMed:15738389, PubMed:18826952, PubMed:22586274). Involved in proteasome homeostasis: in response to proteasome inhibition, mediates the 'bounce-back' of proteasome subunits by translocating into the nucleus and activating expression of genes encoding proteasome subunits (PubMed:20385086, PubMed:21536885, PubMed:23816881). Also involved in regulating glucose flux (PubMed:25041126). Together with CEBPB; represses expression of DSPP during odontoblast differentiation (By similarity). In response to ascorbic acid induction, activates expression of SP7/Osterix in osteoblasts (PubMed:17510056).By similarity17 Publications

Caution

its topology is subject to discussion. According to some groups, it has a single-pass type II membrane protein in normal conditions and is retrotranslocated into a single-pass type III membrane protein in response to stress. According to other reports, it is integrated into the endoplasmic reticulum membrane via multiple membrane-spanning alpha-helices (PubMed:20629635, PubMed:26268886).2 Publications
Was initially thought to be either inactive as transcription factor or to repress transcriptional activation mediated by other isoforms (PubMed:9580677). The presence of the transmembrane region at the N-terminus may explain the inability to observe transcription factor activity.1 Publication

Embryonic lethality: embryos progress normally to the late egg cylinder stage at approximately 6.5 days post coitus (dpc), but development is arrested before 7.5 dpc (PubMed:9087432, PubMed:9501099). Mutant embryos fail to form a primitive streak and lack detectable mesoderm (PubMed:9087432). Homozygous embryos suffer from anemia as a result of abnormal fetal liver erythropoiesis (PubMed:9501099). No defect in globin gene expression are detected; abnormal red cell production being the result of a defect in the fetal liver microenvironment specific for erythroid cells (PubMed:9501099). Mice lacking both Nfe2l1 and Nfe2l2 die early between embryonic days 9 and 10 and exhibit extensive apoptosis due to marked oxidative stress in cells that is indicated by elevated intracellular reactive oxygen species levels and cell death (PubMed:12968018). Conditional knockout mice lacking Nfe2l1 in the liver do not show any liver damage when they are maintained in an unstressed condition (PubMed:15738389). In oxidative stress condition, they develop hepatic cancer following steatosis, apoptosis, necrosis, inflammation, and fibrosis (PubMed:15738389). Hepatocyte-specific deletion causes liver damage resembling the human disease non-alcoholic steatohepatitis (PubMed:18826952). Liver of conditional knockout mice lacking Nfe2l1 show massive hepatic cholesterol accumulation and damage due to inability to mediate response to cholesterol excess (PubMed:29149604). Conditional knockout mice lacking Nfe2l1 in the brain show proteasome impairment and progressive degeneration in cortical neurons (PubMed:21554501, PubMed:21536885).8 Publications

Cleaved at Leu-104 by the aspartyl protease DDI2 following retrotranslocation, releasing the protein from the endoplasmic reticulum membrane and forming the transcription factor NRF1 that translocates into the nucleus.

N-glycosylated in normal conditions, when it has a single-pass type II membrane protein topology, with the DNA-binding domain facing the endoplasmic reticulum lumen (PubMed:17705787, PubMed:18990090).
