MA5-13065 targets Estrogen Receptor in ChIP, GS, IP, and WB applications and shows reactivity with Bovine, Canine, Chicken, Hamster, Human, mouse, Ovine, Porcine, Rabbit, and Rat samples. The TE111.5D11 clone was developed against the entire ER ligand binding domain (LBD), but has greatest affinity for ER-alpha. Because ER-alpha and ER-beta share 50-60% homology, MA5-13065 recognizes ER-beta1 with lower affinity.
The MA5-13065 immunogen is 35kDa, C-terminal fragment (aa 302-595) of human ER expressed in E. coli.
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.
