[[http://www.uniprot.org/uniprot/ESR2_RAT ESR2_RAT]] 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. Isoform 3 and isoform 4 are unable to bind DNA and activate transcription due to the truncation of the DNA binding domain. Isoform 2 shows loss of ligand binding affinity and suppresses ER-alpha and ER-beta1 mediated transcriptional activation and may act as a dominant negative regulator of estrogen action.
