anti-ESR2 antibody
Mouse anti human estrogen receptor beta 5, clone 5/25 specifically recognizes human estrogen receptor beta 5 (ERB5), a splice variant of the nuclear receptor hormone ERbeta (ESR2), shown to exist in at least five isoforms (ERB1-ERB5)(Moore et al. 1998). Although only the ERB1 variant appears fully functional, the remaining isoforms have been shown to form heterodimers with ERB1, thereby enhancing transcription (Shaaban et al. 2008). Immunohistochemical studies have revealed a ubiquitous expression of ERB5 in normal colorectal tissue, and to be present in all primary colorectal carcinomas studied, see Wong, N. et al. for details. The detection of estrogen (ER) and progesterone (PR) receptors using immunohistochemical staining of formal fixed paraffin embedded (FFPE) tissue, has gradually replaced ligand binding assays (LBA), to become the most common method for the determination of the ER/PR status of breast tumors. Approximately 75% to 80% of breast tumors have estrogen and/or progesterone receptors, and the presence of these receptors helps determine both the patient's prognosis and the effectiveness of hormonal therapy transcription (Shaaban et al. 2008, Collins et al. 2009).

Published customer image: Immunoexpression of ERs in endometrial cancers. Tissues were classified as well (A-D), moderately (E-H) or poorly (J-M) differentiated; main panels show closely adjacent sections from three cancer blocks to allow direct comparisons. All proteins were immunolocalised to cell nuclei (see higher power inserts in panels e, f, c and d respectively). In the well and moderately differentiated cancers expression was most intense in epithelial cell layers (arrowheads, panel A and inserts). Note that ERa was low/absent in poor grade cancers (J) but immunoexpression of ERbeta1, 2, 5 was readily detected (K. L, M). Inserts in panels K, L, and M show negative controls for ERbeta1, ERbeta2 and ERbeta5 antibodies respectively generated using primary antibodies pre-absorbed with specific peptides used for immunisation.

NCBI Summary for ESR2
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. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been fully characterized.

UniProt Comments for ESR2
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.
