MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a phosphatidylinositol (PI) 4-kinase which catalyzes the first committed step in the biosynthesis of phosphatidylinositol 4,5-bisphosphate. The mammalian PI 4-kinases have been classified into two types, II and III, based on their molecular mass, and modulation by detergent and adenosine. The protein encoded by this gene is a type III enzyme that is not inhibited by adenosine. [provided by RefSeq, Sep 2014]
PHENOTYPE: Mice homozygous for a targeted knock-out or knock-in conditionally activated exhibit premature death associated with degeneration of mucosal cells in the stomach and intestines. Mice homozygous for a knock-out allele exhibit early embryonic lethality. [provided by MGI curators]
