Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1/ER-alpha, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner.; Lacks ligand binding ability and has no or only very low ERE binding activity resulting in the loss of ligand-dependent transactivation ability. ER beta Protein, Human, Recombinant (E. coli, His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 39.8 kDa and the accession number is Q92731.
