NFE2L2（nuclear factor， erythroid 2 like 2），癌症关联基因，基因ID：4780，这个基因编码一个转录因子，它是碱性亮氨酸拉链（bzip）蛋白的一个小家族的成员。编码的转录因子调节启动子中含有抗氧化反应元件（are）的基因；其中许多基因编码参与对损伤和炎症反应的蛋白质，包括自由基的产生。编码不同亚型的多个转录变体已经被鉴定为该基因。[由RefSeq提供，2015年9月]This gene encodes a transcription factor which is a member of a small family of basic leucine zipper (bZIP) proteins. The encoded transcription factor regulates genes which contain antioxidant response elements (ARE) in their promoters; many of these genes encode proteins involved in response to injury and inflammation which includes the production of free radicals. Multiple transcript variants encoding different isoforms have been characterized for this gene. [provided by RefSeq， Sep 2015]。
