Oestrogens are capable of inducing rat prolactin gene transcription through liganded Oestrogen Receptor (ER) binding a degenerate oestrogen response element (ERE) sequence on the promoter 1440 bp upstream of the transcription start site. ER binding is thought to interact with DNA bound Pit-1 leading to chromatin looping bringing enhancer elements into proximity with the transcription start site. This ERE sequence, TGTCActaTGTCA, differs from the consensus GGTCAnnnTGACC by two ...
