Crystal structure of estrogen receptor beta complexed with 3-Bromo-6-hydroxy-2-(4-hydroxy-phenyl)-inden-1-one

Publication Abstract from PubMed

The syntheses of a series of 2-arylindene-1-ones as potent ligands of ERbeta and ERalpha are described. Several compounds exhibited high potency and moderate selectivity for the ERbeta receptor. X-ray and modeling studies were used to understand ligand binding orientation and observed affinity.

Function

[ESR2_HUMAN] Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Isoform beta-cx lacks ligand binding ability and has no or only very low ere binding activity resulting in the loss of ligand-dependent transactivation ability. DNA-binding by ESR1 and ESR2 is rapidly lost at 37 degrees Celsius in the absence of ligand while in the presence of 17 beta-estradiol and 4-hydroxy-tamoxifen loss in DNA-binding at elevated temperature is more gradual.
