The function of ENSG00000141401 (IMPA2, inositol monophosphatase 2) is as follows. Phosphatase that can use myo-inositol monophosphates, myo- inositol 1,4-diphosphate, scyllo-inositol-1,4-diphosphate, glucose-1- phosphate, beta-glycerophosphate and 2'-AMP as substrates in vitro (PubMed:17068342). It is likely that IMPA2 has an as yet unidentified in vivo substrate(s) (PubMed:17068342). Has been implicated as the pharmacological target for lithium (Li(+)) action in brain (PubMed:17068342). .
