Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified E B IC IF
Estrogen receptor alpha (ER alpha), a member of the steroid receptor superfamily, contains highly conserved DNA binding
(DBD) and ligand binding domains (LBD) (1). Through its estrogen-independent and estrogen- dependent activation domains (AF-1 and AF-2, respectively), ER alpha regulates transcription by recruiting coactivator proteins and interacting with general transcriptional machinery (2). Phosphorylation provides an important mechanism to regulate ER alpha activity (3,4). ER alpha is phosphorylated on multiple sites (5). Serines 104 and 106 are located in the N-terminal transcription activation function domain AF-1, and phosphorylation of Ser104/106 plays an important role in regulating ER alpha activity (5).

ConcentrationNot determined
FormSupplied as liquid in 10mM HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol. No preservative added.
PurityPurified by Protein A affinity chromatography.
ImmunogenSynthetic phospho-Ser104/106 peptide (KLH coupled) corresponding to residues surrounding Ser104/106 of human ER alpha.
SpecificityDetects overexpressed levels of Ser104/106 phosphorylated ER alpha. Detects ER alpha only when phosphorylated at Ser104/106. It does not crossreact with phosphorylated ER isoform beta. Species Crossreactivity: Predicted to react with the specified phosphorylated motif from mouse and equine based on sequence homology.
