D-myo-Inositol-1,3,4-triphosphate sodium

D-myo-Inositol-1,3,4-triphosphate (sodium) is one of the inositol polyphosphate isomers involved in signal transduction. It increases intracellular levels of Ins (3,4,5,6) -P4 by inhibiting the activity of Ins (3,4,5,6) -P4 kinase, which in turn suppresses calcium-activated chloride channels. This compound is regulated by cytoplasmic free calcium levels.
