Description:
This gene encodes a transcription factor (TF) which is a member of a small family of basic leucine zipper (bZIP) proteins. The encoded TF 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. It was associated with erythroid differentiation and shown to play a direct role in globin gene regulation through modulation of the chromatin structure in the β-globin locus. NRF2 can regulate γ-globin expression through binding at the HS2 site of the locus control region (βLCR). Specifically, NRF2 forms heterodimers with small MAF proteins to mediate looping between the βLCR and γ-globin promoters to activate transcription. The miR-144 represses NRF2 gene expression and decreases binding in the γ-globin ARE, leading to repression of γ-globin gene transcription and low fetal haemoglobin (HbF) in normal and sickle erythroid cells. NRF2-ablation studies in a humanized SCD mouse model have shown reduction in HbF expression during gestational erythropoiesis and severity of the SCD phenotype. NRF2 is a candidate regulator of HbF expression.
