MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Phosphatidylinositol 3-kinase is composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. The protein encoded by this gene represents the catalytic subunit, which uses ATP to phosphorylate PtdIns, PtdIns4P and PtdIns(4,5)P2. This gene has been found to be oncogenic and has been implicated in cervical cancers. A pseudogene of this gene has been defined on chromosome 22. [provided by RefSeq, Apr 2016]
PHENOTYPE: Homozygous null or knock-in mutations of this gene lead to embryonic death associated with growth retardation, vascular defects and hemorrhage. Surviving mice homozygous for a knock-in allele show impaired lymphangiogenesis, ascites, reduced weight, and resistance to Ras-driven skin tumorigenesis. [provided by MGI curators]
