The ETS1 (Phospho-Ser251) antibody is a specialized tool used to detect the transcription factor ETS1 when phosphorylated at serine residue 251. ETS1. a member of the ETS family of DNA-binding proteins, regulates gene expression involved in cell proliferation, differentiation, apoptosis, angiogenesis, and immune responses. Its activity is tightly modulated by post-translational modifications, including phosphorylation, which alters its DNA-binding affinity, protein stability, or interactions with cofactors. Phosphorylation at Ser251. located within the regulatory domain of ETS1. has been implicated in fine-tuning its transcriptional activity. Studies suggest this modification may be mediated by kinases such as AKT or MAPK in response to extracellular signals, linking ETS1 to pathways like PI3K/AKT or RAS/MAPK signaling.
The ETS1 (Phospho-Ser251) antibody is crucial for investigating context-specific roles of ETS1 in diseases, particularly cancer, where dysregulated phosphorylation may drive tumor progression, metastasis, or therapy resistance. It enables researchers to study spatial-temporal activation of ETS1 in tissues or cell lines via techniques like Western blotting, immunofluorescence, or immunohistochemistry. Validation of this antibody typically includes knockout controls or phosphatase treatment to confirm specificity. Understanding Ser251 phosphorylation provides insights into how microenvironmental cues or therapeutic agents modulate ETS1-dependent pathways, offering potential biomarkers or targets for precision medicine.
