Product Specifications

Immunogen

Recombinant human ER alpha/NR3A1 alpha protein (aa2-185) (Uniprot: P03372)

Localization

Nuclear

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. This monoclonal antibody is excellent for staining of formalin-fixed, paraffin-embedded breast carcinomas.

Background: ER alpha/NR3A1

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).
