A comparative study of the interaction of oestradiol and the steroidal pure antioestrogen, ICI 164,384, with the molybdate-stabilized oestrogen receptor.
Journal of Steroid Biochemistry 1990 March
The kinetics of binding of oestradiol and the steroidal pure antioestrogen ICI 164,384 to the molybdate-stabilized oestrogen receptor, partially purified from pig and human uterine tissue, were determined. ICI 164,384 bound directly to the oestrogen receptor protein and the kinetic parameters of this interaction were, in general, similar to those for the binding of oestradiol, regardless of the source of the receptor protein. However, the rate of association of oestradiol, regardless of the source of the receptor protein. However, the rate of association of the antagonist with the receptor protein was slower when compared to that of oestradiol. Furthermore, the concentration of binding sites for the two ligands was of the same order. The binding of oestradiol resulted in a steroid-receptor complex which could be transformed in vitro, to a form with increased affinity for DNA-cellulose. However, the complex formed between ICI 164,384 and the receptor protein did not show increased affinity for DNA-cellulose when exposed to conditions that transformed agonist-receptor complexes. Therefore, the binding of ICI 164,384 to the oestrogen receptor protein results in a suppression of the transformation process. A similar suppression in vivo may account for the pure antagonist properties of ICI 164,384.
