%X Nuclear factor erythroid 2-related factor 1 (NFE2L1, also known as Nrf1) is a crucial member of the CNC-bZIP subfamily of transcription factors expressed ubiquitously throughout our body. Recent findings have revealed its association with various metabolic processes, encompassing glucose, lipid, and protein metabolism. In the realm of glucose metabolism, NFE2L1 exerts regulatory control by modulating pancreatic β cells and insulin production. It also influences glucose metabolism in liver and the insulin sensitivity of adipose tissue. Regarding lipid metabolism, NFE2L1 governs this process by influencing the expression of specific adipogenic and lipolysis genes in both liver and adipose tissue. Additionally, NFE2L1 regulates specific lipids, such as cholesterol. These involvements underlie various manifestations of NFE2L1 deficiency such as adipocyte hypertrophy, inflammation, and steatohepatitis. In the realm of protein metabolism, NFE2L1 serves as a major transcription factor regulating the 26S proteasome genes expression, which dysfunction has been related with multiple diseases including neurodegenerative diseases, cancers, autoimmune conditions, etc. In this comprehensive review, we summarize the diverse roles that NFE2L1 plays in glucose, lipid, and protein metabolism, as well as its impact on diseases related to these metabolic processes.
