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.

Publication Abstract from PubMed

Benzopyrans are selective estrogen receptor (ER) beta agonists (SERBAs), which bind the ER subtypes alpha and beta in opposite orientations. Here we describe the synthesis of a late stage intermediate that allowed us to combine A-ring and C-ring modifications and carry out simultaneous SAR studies at both positions. Modification of both positions proved additive, maintaining affinity and improving ERbeta selectivity up to 83-fold. An X-ray cocrystal structure confirms the previously observed binding mode in ERbeta.
