| Function (UniProt annotation) | |||
| Responsible for the provision of inositol required forsynthesis of phosphatidylinositol and polyphosphoinositides andhas been implicated as the pharmacological target for lithiumaction in brain Has broad substrate specificity and can use myo-inositol monophosphates, myo-inositol 1,3-diphosphate, myo-inositol 1,4-diphosphate, scyllo-inositol-phosphate, D-galactose1-phosphate, glucose-1-phosphate, glucose-6-phosphate, fructose-1-phosphate, beta-glycerophosphate, and 2'-AMP as substrates | |||
| Catalytic Activity (UniProt annotation) | |||
| Myo-inositol phosphate + H(2)O = myo-inositol+ phosphate Alpha-D-galactose 1-phosphate + H(2)O = D-galactose + phosphate | |||
