Expand Collapse ESR1  - General Description The ESR1 gene encodes an estrogen receptor, which is a ligand-activated transcription factor composed of hormone binding domain, DNA binding domain, and transcription activation domain. The protein localizes to the nucleus, where it forms homodimers, or heterodimerizes with ESR2. Transactivation in the nucleus involves either direct homodimer binding to an estrogen response element (ERE) sequence, or association with other DNA-binding transcription factors such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3 to mediate ERE-independent signaling. Mutual trans-repression occurs between the ESR and NF-kapa-B in a cell-type specific manner. Alternative promoter usage and alternative splicing result in dozens of transcript variants, but the full length nature of many of these variants has not been determined. Estrogen and its receptors are essential for sexual development and reproductive function, but also play a role in other tissues such as bone.
