Amino acids LLSHVRHARYAP from the C-terminus of human Estrogen Receptor beta 5 were used as the immunogen for the Estrogen Receptor beta 5 antibody.
This MAb specifically recognizes human estrogen receptor beta 5 (ERB5), a splice variant of the nuclear receptor hormone ER beta (ESR2), shown to exist in at least five isoforms (ERB1-ERB5). No cross-reactivity is seen with estrogen receptor beta 1 or 2 isoform. This gene encodes a member of the family of estrogen receptors and superfamily of nuclear receptor transcription factors. The gene product contains an N-terminal DNA binding domain and C-terminal ligand binding domain and is localized to the nucleus, cytoplasm, and mitochondria. Upon binding to 17beta-estradiol or related ligands, the encoded protein forms homo- or hetero-dimers that interact with specific DNA sequences to activate transcription. Some isoforms dominantly inhibit the activity of other estrogen receptor family members.
