We have previously shown that protein-protein interactions mediate cooperative binding of the glucocorticoid receptor DNA-binding domain to a glucocorticoid response element (Dahlman-Wright, K., Siltala-Roos, H., Carlstedt-Duke, J., and Gustafsson, J.-A. (1990) J. Biol. Chem. 265, 14030-14035). The cooperativity of DNA binding is lost when the distance between the two half-sites constituting a glucocorticoid responsive element is altered or when their relative orientation is changed. We show here that mutations in the responsive element which interfere with cooperative DNA binding by the glucocorticoid receptor DNA-binding domain in vitro also abolish transactivation by the full length glucocorticoid receptor in vivo. We also identify a short segment in the proximity of one of the bound zinc ions that is required for cooperative binding of the glucocorticoid receptor DNA-binding domain to a glucocorticoid response element. We suggest that this segment is involved in dimer formation of the native glucocorticoid receptor and that it is important for correct positioning of the dimeric molecule on the double helix of DNA.
