We have shown that the promoter of the human beta‐globin gene contains three regions in addition to the known CAC, CAAT and TATA box regions that are important for the induction of transcription in erythroid cells. By using DNaseI footprinting and gel mobility shift assays we were able to show that two of these regions bind the erythroid specific nuclear factor NF‐E1 (and ubiquitous factors). The third region binds a ubiquitous CAAT‐box factor (CP1). Deletion experiments suggest that only the combination of NF‐E1 and CP1 binding sites, but not each of the sites alone, are capable of mediating the induction of transcription of a minimal (CAC, CAAT, TATA box) beta‐globin promoter in mouse erythroleukaemia (MEL) cells.
