Responsible for the provision of inositol required for synthesis of phosphatidylinositol and polyphosphoinositides and has been implicated as the pharmacological target for lithium action in brain. Has broad substrate specificity and can use myo-inositol 1,3-diphosphate, myo-inositol 1,4-diphosphate, scyllo-inositol-phosphate, glucose-1-phosphate, glucose-6-phosphate, fructose-1-phosphate, beta-glycerophosphate, and 2'-AMP as substrates (By similarity). Is equally active with myo-inositol monophosphate and D-galactose 1-phosphate.By similarity1 Publication

This protein is involved in step 2 of the subpathway that synthesizes myo-inositol from D-glucose 6-phosphate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Inositol-3-phosphate synthase 1 (Isyna1)
  2. Inositol monophosphatase 3 (Impad1), Inositol-1-monophosphatase (Impa1), Inositol-1-monophosphatase (Impa2), Inositol monophosphatase 1 (Impa1), Inositol monophosphatase 2 (Impa2)
This subpathway is part of the pathway myo-inositol biosynthesis, which is itself part of Polyol metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes myo-inositol from D-glucose 6-phosphate, the pathway myo-inositol biosynthesis and in Polyol metabolism.
