Structural insights into the mechanisms of agonism and antagonism in oestrogen receptor isoforms

Eur J Cancer. 2000 Sep;36 Suppl 4:S17-8. doi: 10.1016/s0959-8049(00)00207-0.


Here we summarise the results that have emerged from our structural studies on the oestrogen receptor (ER) ligand-binding domain. We have investigated the conformational effects of a variety of ligands on the structures of both ER isoforms. Each class of ligand (agonists, partial agonists and selective oestrogen receptor modulators) induces a unique conformation in the receptor's ligand-dependent transcriptional activation function. Together these studies have broadened our understanding of ER function by providing a unique insight into ER's ligand specificity and the structural changes that underlie receptor agonism and antagonism.
