Anti-STXBP4 / Syntaxin-binding protein 4

0.5mg/ml if reconstituted with 0.2ml sterile DI water. STXBP4 antibody is used in research to study cellular trafficking and membrane dynamics. The encoded protein, syntaxin-binding protein 4, belongs to the Sec1/Munc18 family, which plays an essential role in the regulation of SNARE-mediated vesicle fusion. STXBP4 interacts with syntaxins to control the docking and fusion of vesicles with target membranes, a process fundamental to intracellular transport, receptor recycling, and signal transduction. Through its role in vesicular trafficking, STXBP4 contributes to the maintenance of cellular polarity, nutrient uptake, and receptor turnover.STXBP4 is particularly significant in processes related to glucose metabolism. It has been shown to regulate the trafficking of the glucose transporter GLUT4 to the plasma membrane in muscle and adipose tissue. This regulation is critical for insulin-stimulated glucose uptake, linking STXBP4 directly to metabolic homeostasis. Alterations in its expression or activity have been connected to insulin resistance and type 2 diabetes, making it an important subject of investigation in metabolic disease research. Beyond glucose regulation, STXBP4 participates in broader endocytic and exocytic pathways that influence receptor signaling and cellular communication.Studies suggest that STXBP4 may also contribute to cancer biology. Dysregulated expression has been observed in certain tumor types, where altered vesicle trafficking can affect growth factor signaling and proliferation. Research is ongoing to determine whether STXBP4 serves as a biomarker for cancer progression or a potential therapeutic target. Its involvement in vesicle-mediated signaling suggests that it may influence multiple pathways central to tumor growth and survival.At the molecular level, STXBP4 is characterized by conserved domains that enable binding to syntaxins and interaction with SNARE complexes. This interaction stabilizes vesicle docking and coordinates the timing of fusion events. Experimental models demonstrate that modulation of STXBP4 can alter the efficiency of GLUT4 vesicle fusion, highlighting its central role in metabolic regulation. Antibody-based approaches are frequently used to assess protein levels, localization, and interactions within these pathways.The STXBP4 antibody is widely applied in techniques such as western blotting, immunohistochemistry, immunofluorescence, and flow cytometry. These applications allow scientists to investigate expression across tissues, examine subcellular distribution, and evaluate changes in disease states. When used alongside functional assays, STXBP4 detection provides valuable insight into vesicle trafficking and its consequences for metabolism and signaling. For investigators examining insulin action, metabolic disorders, or vesicular transport, the STXBP4 antibody is a reliable and versatile research tool.
