D-myo-inositol (1,4,5)-trisphosphate is a secondary messenger molecule used in signal transduction and lipid signaling in eukaryotic cells. It mediates the biological response of a large number of hormones and neurotransmitters in target cells by regulating calcium release from intracellular stores. D-myo-inositol (1,4,5)-trisphosphate is synthesized by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, by the action of phospholipase C, as described in D-myo-inositol (1,4,5)-trisphosphate biosynthesis.

Once formed, the levels of D-myo-inositol (1,4,5)-trisphosphate are tightly regulated by two mechanisms.

In the first mechanism, which is described in this pathway, the compound is dephosphorylated in three successive steps, via D-myo-inositol (1,4)-bisphosphate and 1D-myo-inositol 4-monophosphate [Downes82, Storey84], providing myo-inositol that can be recycled to the plasma membrane as posphatidylinositol.

In the second mechanism, D-myo-inositol (1,4,5)-trisphosphate is phosphorylated further to generate additional phosphoinositol compounds, many of which play key roles in various cellular processes (see D-myo-inositol (1,3,4)-trisphosphate biosynthesis).
