Reference: Ohnishi T et al.(2007) Spatial expression patterns and biochemical properties distinguish a second myo-inositol monophosphatase IMPA2 from IMPA1 J. Biol. Chem. 1: 637-646 [PMID: 17068342]

Interaction Information:

Comment Lithium inhibits IMPase activity of IMPA1. However, concentrations of lithium in excess of the therapeutic range are needed to inhibit IMPase activity from IMPA2 when myo-inositol 1-monophosphate is used as a substrate. Both isoforms display a substantial different sensitivity to lithium depending on the substrates used. This indicates that myo-inositol 1-monophosphate is not the optimal substrate for IMPA2.
