Estrogen-related receptor gamma (ERR-gamma), also known as NR3B3 (nuclear receptor subfamily 3, group B, member 3), is a member of nuclear hormone receptor family of steroid hormone receptors. As an orphan nuclear receptor, it binds specifically to an estrogen response element and activates reporter genes controlled by estrogen response elements. It behaves as a constitutive activator of transcription. 4-hydroxytamoxifen and diethylstilbestrol may act as inverse agonists and deactivate ESRRG. It also seems to be the target of bisphenol A. This antibody is a rabbit polyclonal antibody raised against residues near the C terminus of human ESRRG.
