Protein
Inositol monophosphatase 2
Gene
Impa2
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Can use myo-inositol monophosphates, scylloinositol 1,4-diphosphate, glucose-1-phosphate, beta-glycerophosphate, and 2'-AMP as substrates. Has been implicated as the pharmacological target for lithium Li+ action in brain By similarity.

Catalytic activityi

Myo-inositol phosphate + H2O = myo-inositol + phosphate.

Cofactori

Magnesium By similarity.
