D-myo-Inositol-1,2,4,5,6-pentaphosphate sodium salt

D-myo-Inositol-1,2,4,5,6-pentaphosphate (Ins (1,2,4,5,6) P5) sodium salt is one of several inositol polyphosphate isomers involved in signal transduction. In human Jurkat T lymphocytes, Ins (1,2,4,5,6) P5 (sodium salt) is phosphorylated by 1/3 kinase to form InsP6. This compound plays a role in calcium signaling pathways.
