MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This locus encodes an inositol monophosphatase. The encoded protein catalyzes the dephosphoylration of inositol monophosphate and plays an important role in phosphatidylinositol signaling. This locus may be associated with susceptibility to bipolar disorder. [provided by RefSeq, Jan 2011]
PHENOTYPE: Mice homozygous for a null gene trap mutation do not exhibit an overt mutant phenotype. Male mice homozygous for a knock-out alle exhibit increased prepulse inhibition. [provided by MGI curators]
