Product Specific Information
PA1-311 detects estrogen receptor (ER) beta from human, non-human primate, mouse, ovine, and rat tissues.
It has been successfully used in Western blot, immunocytochemistry, and gel shift procedures.
By Western blot, this antibody detects an ~55–62 kDa protein representing ER beta from rat brain homogenate.
PA1-311 efficiently supershifts rat ER beta/ER response element (vitellogenin xenopus A2 gene).
The immunogen is a synthetic peptide corresponding to residues A(55) E P Q K S P W C E A R S L E H(70) of rat ER beta.
Recombinant ER beta expressed in baculovirus system (Cat. # RP-311 and RP-312) can be purchased for control experiments in Western blot and gel shift assays.
PA1-311 can be used with blocking peptide PEP-011.
Target Information
Estrogen Receptor beta (ER beta, NR3A2) protein is approximately 55 kDa, though multiple isoforms ranging from 36–59 kDa have been described.
Human ER beta was initially cloned and characterized from testis.
Estrogen Receptors (ER) are members of the steroid/thyroid hormone receptor superfamily of nuclear receptors.
The estrogen receptor is a ligand-activated transcription factor that, when bound to estrogen hormone, induces a conformational change allowing dimerization and binding to estrogen response elements (ERE) in DNA.
When bound to EREs, ER can positively or negatively regulate gene transcription through the recruitment of coactivator or corepressor proteins.
There are two different forms of the estrogen receptor, alpha and beta, encoded by separate genes (ESR1 and ESR2, respectively).
Estrogen receptor beta binds estrogens with an affinity similar to that of estrogen receptor alpha.
Some ER beta isoforms dominantly inhibit the activity of estrogen receptor alpha in reproductive tissues.
ER beta is found widely in many tissues throughout the body and can act as a potent tumor suppressor, playing a crucial role in many cancer types such as prostate cancer, autism spectrum disorder, medullary thyroid carcinoma, De Quervain Disease, and cardiovascular disease risk.
