D-myo-Inositol-1,2,5,6-tetraphosphate, sodium salt

D-myo-Inositol-1,2,5,6-tetraphosphate, sodium salt, is a tetra-phosphorylated derivative of inositol and plays a significant role in cellular signaling pathways. With phosphate groups arranged at the 1, 2, 5, and 6 positions of the inositol ring, this compound provides a valuable model for studying the effects of phosphorylation patterns on cellular signaling networks. It has been instrumental in understanding inositol phosphate metabolism and its regulation of diverse signaling cascades. Researchers often use this compound to investigate its participation in calcium signaling and membrane trafficking. Its specific phosphorylation pattern allows it to act as a regulatory ligand for a variety of enzymes and receptor proteins involved in intracellular signaling. Studies have shown its importance in modulating the activities of phosphatases and kinases, enzymes critical for maintaining cellular homeostasis. In addition, D-myo-Inositol-1,2,5,6-tetraphosphate is widely used in dissecting the molecular interactions that occur within phosphoinositide metabolism. By mapping how this phosphorylation pattern affects protein-protein interactions, researchers gain insights into how inositol phosphates regulate immune responses, apoptosis, and signal transduction. This knowledge is crucial in understanding the broader impact of inositol phosphates on cell growth, differentiation, and metabolic pathways.
