摘要：
Oestrogen receptor (ER) is a ligand-activated transcription factor which plays an important role in many physiological processes. The aim of this study was to explore the difference between agonist and antagonist recognition mode. Molecular dynamics simulation of ER/diethylstilbestrol and ER/4-hydroxytamoxifen complexes was carried out. Our research results indicate that Glu353 participates in both agonist and antagonist recognition; His524 is the key residue in agonist recognition; Met343, Leu346, Thr347 and Asp351 are the key residues in the antagonist recognition.
