PtdIns-(3)-P1 (1,2-dipalmitoyl)-d62 (ammonium salt)

PtdIns-(3)-P1 (1,2-dipalmitoyl)-d62, ammonium salt, is a specialized lipid molecule utilized in research to investigate the signaling pathways involved in cellular processes. Phosphatidylinositol 3-phosphate (PI3P) is a key regulator of various cellular functions, including membrane trafficking, autophagy, and signal transduction. PI3P is generated by phosphorylation of phosphatidylinositol (PI) by class III phosphatidylinositol 3-kinase (PI3K) enzymes. This lipid acts as a recruitment signal for proteins containing specific PI3P-binding domains, facilitating their localization to membrane compartments enriched in PI3P. PtdIns-(3)-P1 (1,2-dipalmitoyl)-d62, ammonium salt, labeled with deuterium (^2H), serves as a valuable tool in lipidomics and cellular imaging studies, allowing for the precise quantification and visualization of PI3P dynamics in living cells and tissues. Researchers employ this stable isotope-labeled lipid to explain the spatiotemporal regulation of PI3P signaling, investigate its role in disease pathogenesis, and identify novel PI3P-interacting proteins. Furthermore, PtdIns-(3)-P1 (1,2-dipalmitoyl)-d62 facilitates the characterization of lipid-protein interactions and the development of strategies targeting PI3P-dependent pathways implicated in cancer, neurodegeneration, and infectious diseases. By providing insights into the molecular mechanisms underlying PI3P-mediated signaling events, this chemical contributes to advancing our understanding of cellular physiology and pathology.
