Nuclear Factor (Erythroid 2) - Like Factor 3, also known as NFE2L3 or 'NRF3', is a transcription factor that in humans is encoded by the Nfe2l3 gene.
This protein is a basic leucine zipper transcription factor belonging to the Cap ‘n’ Collar (CNC) family of proteins. In 1989, the first CNC transcription factor was identified, namely NFE2L2. After that, several other protein members have also been identified over the years like NRF1 and NRF3 in different organisms like humans, mice and zebrafish. These proteins are specifically encoded in the humans by Nfe2l1 and Nfe2l3 genes respectively.
