Abstract: Since estrogens strongly suppress the expression of alpha 2u-globulin genes in the rat liver, we studied the binding of estrogen-receptor complexes to fragments derived from alpha 2u-globulin gene RAO 01 using a DNA-cellulose competition assay. Rat uterus cytosol labelled with [3H]estradiol was used as a source of the estrogen receptor. As a positive control in these experiments we used an oligonucleotide containing the estrogen response element (ERE) cloned into pUC18. Our experiments indicate that estrogen-receptor complexes bind specifically to the ERE and to a fragment of RAO 01 located in the 5'-upstream region (bp -606 up to -575). This fragment is conserved among other members of this gene family. This is the first time that in vitro estrogen receptor binding is observed to gene fragments derived from a gene that is repressed by this steroid in vivo.
