ER-beta a nuclear hormone receptor and transcription factor. Binds and activated by estrogen. Regulates gene expression and affects cellular proliferation and differentiation in target tissues. Binds estrogens with an affinity similar to that of ER-alpha, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Eight alternatively-spliced isoforms have been described. 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. Note: This description may include information from UniProtKB.
