Bach1 is a member of the BTB and CNC transcriptional regulator family that, like Nrf2, binds to ARE sequences as heterodimeric complexes with small Maf proteins [18] A major physiological role for Bach1 is in
iron homeostasis through regulation of the expression of heme oxygenase - 1 (HMOX1), ferroportin (FPN1) and Ferritin (FTH) genes [23], [24], [33], [41].
