Hepatocytes achieve an efficient hormonal control of this promoter through a functional interaction between the estrogen responsive elements and a promoter proximal region upstream of the TATA box , which is characterized by a high density of binding sites for the transcription factors CTF/NF-1 , C/EBP and HNF3 .
