MA3-310 detects estrogen receptor alpha in human and rabbit samples.
MA3-310 has been successfully used in immunohistochemistry, immunoprecipitation and Western blot procedures. By Western blot, this antibody detects a ~68 kDa protein representing estrogen receptor alpha in MCF-7 cells, human breast tumors, and rabbit vaginal tissue. In immunohistochemistry this antibody recognizes the estrogen receptor alpha in MCF-7 cells, human breast tissue, and human smooth muscle cells.
The MA3-310 immunogen is a mix of synthetic peptides corresponding to residuesT(140) V R E A G P P A F Y R P N S(154) and E(247) V G M M K G G I R K D R R G G R(263) of human ER alpha.
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 that allows 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). Due to alternative RNA splicing, at least 4 estrogen receptor-alpha isoforms are known to exist (Isoform 1 (66 kDa), Isoform 2 (53 kDa), Isoform 3 (47 kDa), Isoform 4 (35 kDa)). Estrogen receptors are widely expressed in different tissue types and are essential for sexual development and reproductive function. They also play a role in other tissues such as bone. Estrogen receptors are involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis.
