Inositol monophosphatase 1

UniProtKB accession:  O55023

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Phosphatase involved in the dephosphorylation of myo-inositol monophosphate to generate myo-inositol. Is also able to dephosphorylate scyllo-inositol-phosphate, myo-inositol 1,4-diphosphate, scyllo-inositol-1,3-diphosphate and scyllo-inositol-1,4-diphosphate. Also dephosphorylates in vitro other sugar-phosphates including D-galactose-1-phosphate, glucose-1-phosphate, glucose-6-phosphate, fructose-1-phosphate, beta-glycerophosphate and 2'-AMP. Responsible for the provision of inositol required for synthesis of phosphatidylinositol and polyphosphoinositides, and involved in maintaining normal brain function. Has been implicated as the pharmacological target for lithium Li(+) action in brain.
