背景信息

The Phospho-PTP1B (Ser352) antibody is a specialized tool for detecting the phosphorylated form of Protein Tyrosine Phosphatase 1B (PTP1B) at serine residue 352. PTP1B, a key regulator of metabolic signaling pathways, modulates insulin and leptin receptor signaling by dephosphorylating receptor-associated kinases. Its activity is tightly controlled through post-translational modifications, including phosphorylation. Ser352 phosphorylation, located in the C-terminal region, is associated with altered PTP1B enzymatic activity, substrate specificity, or subcellular localization, potentially influencing its role in metabolic disorders like obesity and type 2 diabetes. Studies suggest this modification may occur in response to cellular stress or insulin stimulation, linking it to pathways involving ERK or other serine/threonine kinases. The antibody is widely used in research to investigate PTP1B's regulatory mechanisms in metabolic diseases, cancer, and neurodegenerative conditions. Validated for applications such as Western blotting, immunoprecipitation, and immunofluorescence, it provides critical insights into phosphorylation-dependent PTP1B behavior. Researchers rely on its specificity to explore therapeutic targeting of PTP1B, particularly in contexts where dysregulated phosphorylation contributes to insulin resistance or oncogenic signaling. Proper controls, including knockout validation, are recommended to ensure accurate detection.
