Used in biochemical research as a stable analog of inositol 1,2,3,4,5,6-hexakisphosphate (IP6), aiding in the study of cellular signaling pathways. It acts as an inhibitor of enzymes that interact with IP6, such as kinases and phosphatases, helping to elucidate their regulatory roles. Also employed in structural biology to stabilize protein complexes involving IP6-binding sites. Its high negative charge mimics the natural ligand, making it valuable in assays investigating molecular interactions in signal transduction and gene expression.
