Estrogen-related receptor gamma
Lua error in Module:Infobox_gene at line 33: attempt to index field 'wikibase' (a nil value). Estrogen-related receptor gamma (ERR-gamma), also known as NR3B3 (nuclear receptor subfamily 3, group B, member 3), is a nuclear receptor that in humans is encoded by the ESRRG (EStrogen Related Receptor Gamma) gene.[1][2][3] It behaves as a constitutive activator of transcription.[4]
This protein is a member of nuclear hormone receptor family of steroid hormone receptors. No physiological activating ligand is known for this orphan receptor, but 4-hydroxytamoxifen and diethylstilbestrol act as inverse agonists and deactivate ESRRG.[5] It also seems to be the target of bisphenol A (see below).
Bisphenol A binding

There is evidence that bisphenol A functions as an endocrine disruptor by binding strongly to ERR-γ.[4] BPA as well as its nitrated and chlorinated metabolites seems to binds strongly to ERR-γ (dissociation constant = 5.5 nM), but not to the estrogen receptor (ER).,[4][6] BPA binding to ERR-γ preserves its basal constitutive activity.[4] It can also protect it from deactivation from the selective estrogen receptor modulator 4-hydroxytamoxifen.[4]
Different expression of ERR-γ in different parts of the body may account for variations in bisphenol A effects. For instance, ERR-γ has been found in high concentration in the placenta, explaining reports of high bisphenol A accumulation there.[7]
