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 allowing dimerization and binding to estrogen response elements (ERE) in DNA. ER can regulate gene transcription through coactivator or corepressor recruitment.
There are two forms of the estrogen receptor, alpha and beta, encoded by separate genes (ESR1 and ESR2). Due to alternative RNA splicing, at least four estrogen receptor-alpha isoforms exist:
- Isoform 1 (66 kDa)
- Isoform 2 (53 kDa)
- Isoform 3 (47 kDa)
- Isoform 4 (35 kDa)
Estrogen receptors are widely expressed in various tissues, essential for sexual development and reproduction, and also function in bone and other tissues. They are involved in pathological processes such as breast cancer, endometrial cancer, and osteoporosis.
