Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
The estrogen receptor alpha (ERa), a transcription factor that controls the expression of a number of genes involved in cellular differentiation and proliferation in a wide variety of tissues, is regulated by ligand binding and phosphorylation. ER contains at least two transcriptionally active domains: constitutively active F-1 at the ER N-terminus of the protein and ligand-dependent AF-2 at the ER C-terminus. Although ligand binding is considered essential for the full activation of ER, it has long been recognized that the receptor is subject to post-translational alterations, such as phosphorylation, which also regulated its activity. ER phosphorylation patterns appear to be cell type-specific. Serine 167 has been shown to be phosphorylated by p90rsk1 in vitro and to regulate ER AF-1-dependent transcriptional activation in vivo.
