| Estrogen Receptor _ (Tyr-537), Phosphospecific Antibody |
| WB |
| The antibody was cross-adsorbed to unphosphorylated ER_ (Tyr-537) peptide before affinity purification using phospho-ER_ (Tyr-537) peptide (without carrier). This antibody detects several forms of ER_ ranging from 66 to 35 kDa* on SDS-PAGE immunoblots of MCF-7 cells treated with pervanadate, and this reactivity is removed after alkaline phosphatase treatment. This sequence is well conserved in rat and mouse ER_, and is also well conserved in ER_ (Tyr-488). |

| Estrogen receptor _ (ER_) is a member of the steroid receptor superfamily and its structure includes an N-terminal ligand-independent transactivation domain (AF-1), a highly conserved DNA binding domain, and a C-terminal ligand-dependent transactivation domain (AF-2). AF-1 and AF-2 activate transcription independently and synergistically, and act in a promoter- and cell-specific manner. Phosphorylation at multiple sites provides an important mechanism to regulate ER_ activity. Ser-104, Ser-106, Ser-118, and Ser-167 are located in the amino-terminal transcription activation function domain AF-1, and phosphorylation of these serine residues plays an important role in regulating ER_ activity. In addition to these sites, phosphorylation of Tyr-537 has been implicated in maximal hormone binding, dimerization, and transcriptional activity. Tyr-537, located in the AF-2 domain, is phosphorylated by c-Src leading to nuclear export of ER_ and degradation. Thus, a variety of phosphorylation events control ER_ activity. |
