Product Summary for ER alpha/NR3A1 Antibody (ER506)

Immunogen

Recombinant fragment (around aa 2-185) of human ER alpha/NR3A1 protein (exact sequence is proprietary) (Uniprot: P03372)

Localization

Nucleus

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.

Background: ER alpha/NR3A1

The estrogen receptor (ER) is a ~ 67kDa protein, originally described by Jensen and Jacobson, 1962 as a uterine protein which bound 3H-estradiol with high affinity. More than two decades later the cDNA encoding the human estrogen receptor was finally cloned and sequenced. The estrogen receptor gene consists of more than 140kb of genomic DNA divided into 8 exons, being translated into a protein with six functionally discrete domains, labeled A through F. The A/B domain of the estrogen receptor contains a constitutively active transcription activation function called TAF-1. Domain C contains two Cys4 zinc fingers, which form the core of the DNA binding domain; it also contains a weak constitutive dimerization activity. The zinc fingers interact with DNA, and the ER homodimer appears to bind most tightly to the palindromic estrogen response element (ERE) sequence GGATCNNNGATCC. The hinge domain D appears to be the location for binding by heat shock proteins. The estrogen receptor is an important regulator of growth and differentiation in the mammary gland. Estrogens play an important role also in breast cancer development, although tumors often progress towards an autocrine growth. This hormone-independence and the incomplete correlation between ER-status and response to endocrine (tamoxifen) therapy may be explained by the presence of receptor variants with either constitutive transcriptional activity or a dominant negative inhibition of normal ER function. Many investigators have reported on the isolation of cDNAs which encode variant ER sequences. Many of these variants appear to be formed by errors in RNA splicing which result in one or more exons being lost during processing of the ER message.
