Related Product Information for anti-ESR1 antibody

Estrogen receptor alpha, a NR3 Steroid Receptor, activates transcription of a wide variety of genes in response to estrogen, particularly in reproductive tissues. Recent studies have shown that ER alpha also can function in a ligand-independent and DNA binding- independent manner, as well as through cell-surface signaling. ER alpha functions have also been demonstrated via the selective ER modulator (SERM) ligands and their various ER signaling pathways.

NCBI Description

This gene encodes an estrogen receptor, a ligand-activated transcription factor composed of several domains important for hormone binding, DNA binding, and activation of transcription. The protein localizes to the nucleus where it may form a homodimer or a heterodimer with estrogen receptor 2. Estrogen and its receptors are essential for sexual development and reproductive function, but also play a role in other tissues such as bone. Estrogen receptors are also involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis. 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.
