Steroid receptors recognize bipartite targets composed of six base-pair half-sites. There are two canonical types of half-site which differ only in their central two base pairs. The crystal structure of an estrogen receptor-like DNA-binding domain bound to the wrong type of half-site (a glucocorticoid response element) reveals an interface that resembles the specific interfaces of the glucocorticoid receptor or estrogen receptor bound to their correct response elements ...
