Phospho-ERalpha (Tyr-537) synthetic peptide (coupled to carrier protein) corresponds to amino acids surrounding Tyr-537 in human ERalpha. This sequence is well conserved in rat and mouse ERalpha, and is also well conserved in ERbeta (Tyr-488).

Product Specific Information

The antibody was cross-adsorbed to unphosphorylated ERalpha (Tyr-537) peptide before affinity purification using phospho-ERalpha (Tyr-537) peptide (without carrier). This antibody detects several forms of ERalpha ranging from 66 to 35 kDa* on SDS-PAGE immunoblots of MCF-7 cells treated with pervanadate, and this reactivity is removed after alkaline phosphatase treatment.

Target Information

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.
