Clone Host Grade Applications
Monoclonal Rabbit Purified B
Estrogen receptor a (ERa), 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, (espectively), ERa regulates transcription by recruiting coactivator proteins and interacting with general transcriptional machinery (2). Phosphorylation provides an important mechanism to regulate ERa activity (3,4). ERa is phosphorylated on multiple sites (5). Ser104, 106, 118 and 167 are located in the aminoterminal transcription activation function domain AF-1, and
phosphorylation of these serines plays an important role in regulating ERa activity. Ser118 may be the substrate of the transcription regulatory kinase CDK7 (5). Ser167 may be phosphorylated by p90RSK and Akt (4,6). Phosphorylation of Ser167 may confer tamoxifen resistance in breast cancer patients (4).
