Estrogen Receptor α (ER alpha) is a 65 kDa protein and a member of the steroid family of nuclear receptors. Estrogen Receptor alpha is a ligand-activated transcription factor that, when bound to estrogen, induces a conformational change that allows dimerization and binding to estrogen response element sequences. When bound to DNA, Estrogen Receptor alpha can positively or negatively regulate gene transcription. Like other steroid hormone receptors, Estrogen Receptors are intracellular proteins. Estrogen Receptors play an important role in regulating mammary gland growth and differentiation. Breast tumors that are ER positive may also show a more favorable response to anti-estrogen therapies.

Synthetic peptide directed against human Estrogen Receptor α.
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 splicing results in several transcript variants, which differ in their 5' UTRs and use different promoters. [provided by RefSeq].
FUNCTION:SwissProt: P03372 # Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. SIZE:595 amino acids; 66216 Da
SUBUNIT: Binds DNA as a homodimer. Can form a heterodimer with ESR2. Interacts with NCOA3, NCOA5 and NCOA6 coactivators, leading to a strong increase of transcription of target genes. Interacts with NCOA7 in a ligand-inducible manner. Interacts with PHB2, PELP1 and UBE1C. Interacts with AKAP13. Interacts with CUEDC2. Interacts with JARID1A. Interacts with SMARD1. Interacts with SLC30A9 (By similarity). Interacts with HEXIM1 and MAP1S. Interacts with PBXIP1. SUBCELLULAR LOCATION:Nucleus. DOMAIN:SwissProt: P03372 Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal steroid-binding domain.
PTM: Phosphorylated by cyclin A/CDK2. Phosphorylation probably enhances transcriptional activity. SIMILARITY: Belongs to the nuclear hormone receptor family. NR3 subfamily. & Contains 1 nuclear receptor DNA-binding domain. MISCELLANEOUS:In the absence of ligand, steroid hormone receptors are thought to be weakly associated with nuclear components; hormone binding greatly increases receptor affinity. The hormone- receptor complex appears to recognize discrete DNA sequences upstream of transcriptional start sites.

Usage Statement
Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
Storage and Shipping Information
Storage Conditions
Stable for 1 year at -20ºC from date of receipt.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
