Inositol monophosphatase 2, also known as Inositol-1(or 4)-monophosphatase 2, Myo-inositol monophosphatase A2 and IMPA2, is an enzyme which belongs to the inositol monophosphatase family. IMPA2 catalyzes the dephosphoylration of inositol monophosphate with cofactor Magnesium and Inhibited by high Li+ and restricted Mg2+ concentrations. IMPA2 plays an important role in phosphatidylinositol signaling. IMPA2 can use the myo-inositol monophosphates, scylloinositol 1,4-diphosphate, glucose-1-phosphate, beta-glycerophosphate, and 2'-AMP as substrates. IMPA2 is a pharmacological target for lithium Li(+) action in brain, it is considered to have a role in schizophrenia and bipolar disorder.

IMPA1 (Inositol Monophosphatase 1) is a Protein Coding gene. This gene encodes an enzyme that dephosphorylates Myo-inositol monophosphate to generate free Myo-inositol, a precursor of phosphatidylinositol, and is, therefore, an important modulator of intracellular signal transduction via the production of the second messenger's myoinositol 1,4,5-trisphosphate and diacylglycerol. Despite its many physiological functions, no clinical phenotype has been assigned to this gene dysfunction to date. Additionally, IMPA1 is the main target of lithium, a drug that is at the forefront of treatment for bipolar disorder. IMPA1 is widely expressed in the testis, thyroid, and other tissues. Diseases associated with IMPA1 include Mental Retardation, Autosomal Recessive 59, and Bipolar Disorder.
