Estrogen receptor-alpha (ERα) is a nuclear hormone receptor critical for mediating estrogen signaling in various tissues, including the breast, uterus, and cardiovascular system. Phosphorylation of ERα at specific serine residues, such as Ser106. dynamically regulates its transcriptional activity, protein stability, and interactions with co-regulators. The phosphorylation at Ser106 is associated with ligand-independent receptor activation and has been implicated in modulating ERα’s response to growth factor signaling pathways, including MAPK and CDK2. This post-translational modification may influence receptor dimerization, DNA binding, or recruitment of transcriptional machinery, thereby affecting estrogen-dependent gene expression.
Antibodies targeting ERα phosphorylated at Ser106 (Phospho-Ser106) are essential tools for studying the functional regulation of ERα in physiological and pathological contexts. They are widely used in techniques like Western blotting, immunohistochemistry, and immunofluorescence to detect site-specific phosphorylation status in cell lines, tissues, or clinical samples. Research utilizing these antibodies has highlighted the role of Ser106 phosphorylation in breast cancer progression, particularly in resistance to endocrine therapies like tamoxifen. Aberrant phosphorylation at this site may correlate with aggressive tumor behavior or poor prognosis, offering insights into mechanisms underlying therapeutic resistance.
These antibodies enable researchers to explore the crosstalk between ERα signaling and other oncogenic pathways, aiding the development of targeted strategies to overcome treatment resistance in hormone-dependent cancers.
