ER alpha/NR3A1 Antibody (ER506) [Janelia Fluor® 646] Summary

• Immunogen: Recombinant fragment (around aa 2-185) of human ER alpha/NR3A1 protein (exact sequence is proprietary) (Uniprot: P03372)
• Localization: Nucleus
• Marker: Marker of Estrogen Dependence
• Specificity: This monoclonal antibody is specific to ER alpha and shows minimal cross-reaction with other members of the family. ER is an important regulator of growth and differentiation in the mammary gland. Presence of ER in breast tumors indicates an increased likelihood of response to anti-estrogen (e.g. tamoxifen) therapy. It strongly stains nuclei of epithelial cells in breast carcinomas.
• Isotype: IgG1 Kappa
• Clonality: Monoclonal
• Host: Mouse
• Gene: ESR1
• Purity: Protein A or G purified

Applications/Dilutions

• Dilutions:
  • CyTOF-ready

Background

Estrogen receptor alpha (ER alpha) is a nuclear protein and member of the steroid hormone receptor family. ER alpha possesses both DNA binding and ligand binding domains, and exerts a significant role in activating the transcription of certain genes (1). Ligand-dependent dimerization and phosphorylation on serines, 104, 106, and 118 function to regulate the transcriptional activation of ER alpha (2). The phosphorylation of the human estrogen receptor (ER) serine residue at position 118 is required for full activity of the ER activation function 1 (AF-1) (3).
