transcription factor NF-E2 45 kD subunit; nuclear factor erythroid-derived 2 45 kD subunit; p45 NF-E2; leucine zipper protein NF-E2 (NFE2)

Function: - required for activity at the locus control region (LCR) upstream of the globin gene complexes - requires p18 NF-E2 for binding to the NF-E2 motif - may play a role in all aspects of hemoglobin production: globin synthesis, heme synthesis, & the procurement of iron - interacts with MLL2; leading to activate transcription of the beta-globin locus (putative) - heterodimer of p45 NF-E2 & p18 NF-E2 Structure: - belongs to the bZIP family, CNC subfamily - contains 1 bZIP domain Compartment: nucleus Expression: - expressed in hematopoietic cells - also expressed in colon & testis
