  sub:_5 prov:value "DNase I footprinting showed that the COUP-TF I protein bound to the 5'-flanking region of the oxytocin gene at the site of the distal composite hormone response element, which mediates the responses to estrogen, retinoic acid, and thyroid hormone. Electrophoretic mobility shift assay using this composite hormone response element as probe showed that COUP-TF I and the estrogen receptor competed for binding but did not form a heterodimer. The binding by COUP-TF I was stronger than the binding of the estrogen receptor." ;
