Metabolite Identification
Common NameMyo-inositol 1-phosphate
DescriptionMyo-inositol 1-phosphate is a metabolite of the Inositol phosphate metabolism and the Phosphatidylinositol signaling system. Inositol phosphatases [EC:3.1.3.25] play a crucial role in the phosphatidylinositol signaling pathway; in brain, the expression is substantially higher in the subcortical regions, most prominently in the caudate. The phosphatidylinositol pathway is thought to be modified by lithium, a commonly prescribed medication in treating bipolar disorder. (OMIM 605922 ).
