- Ohnishi T, Ohba H, Seo K, Im J, Sato Y, Iwayama Y, et al. Spatial expression patterns and biochemical properties distinguish a second myo-inositol monophosphatase IMPA2 from IMPA1. J Biol Chem. 2007;282:637-46 pubmed..These data suggest that IMPA2 has a separate function in vivo from that of IMPA1. ..

Ablation of Mrds1/Ofcc1 induces hyper-γ-glutamyl transpeptidasemia without abnormal head development and schizophrenia-relevant behaviors in mice. PLoS ONE. 2011;6:e29499 pubmed publisher..These results prompt further examination of the gene, including its putative contribution to hyper-γ-glutamyl transpeptidasemia and schizophrenia. ..

Human myo-inositol monophosphatase 2 rescues the nematode thermotaxis mutant ttx-7 more efficiently than IMPA1: functional and evolutionary considerations of the two mammalian myo-inositol monophosphatase genes. J Neurochem. 2013;124:685-94 pubmed publisher..Given the ability of human IMPA2 to rescue the ttx-7 mutant, and its genetic association with multiple neuropsychiatric disorders, close scrutiny of IMPA2 function and the evolutionary origin of IMPase genes is warranted. ..
