Abstract excerpt
We have used site-directed mutagenesis and a homologous transient transfection system to investigate the role of the two imperfect estrogen response elements (EREs) located at -302/-334 in the 5'-flanking region of the estrogen-regulated Xenopus laevis vitellogenin B1 gene. Deletion of either ERE effectively abolishes estrogen-dependent transcription of the vitellogenin promoter. Neither replacement of the two...
