NCIt synonyms : ER-Beta; ESR2; Nuclear Receptor Subfamily 3 Group A Member 2; Estrogen Receptor 2; NR3A2;
NCIt definition : Estrogen receptor beta (530 aa, 59 kDa) is encoded by the human ESR2 gene. This protein
is involved in the modulation of transcription of estrogen-responsive genes.;
NCIt note : ESR2 binds estrogens with an affinity similar to ESR1 and transduces extracellular
hormone signals into transcriptional responses by binding ERE DNA as a homodimer or
as a heterodimer with ESR1, NCOA3, NCOA5, or NCOA6 coactivators and activating target
gene expression in an estrogen-dependent manner. Lacking ligand binding ability and
ERE binding activity, isoform Beta-2/CX preferentially forms a heterodimer with ESR1
and inhibits ligand-dependent DNA-binding and transactivation.;
