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 positively or negatively regulate gene transcription through recruitment of coactivator or corepressor proteins.
There are two forms of the estrogen receptor, alpha and beta, encoded by separate genes (ESR1 and ESR2). At least four estrogen receptor-alpha isoforms are known:
- Isoform 1 (66 kDa)
- Isoform 2 (53 kDa)
- Isoform 3 (47 kDa)
- Isoform 4 (35 kDa)
Estrogen receptors are widely expressed and essential for sexual development and reproductive function, also playing roles in bone and various pathological processes such as breast cancer, endometrial cancer, and osteoporosis.
