FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an isoform of the catalytic subunit of phosphoinositide 3-kinase (PI3K). These kinases are important in signaling pathways involving receptors on the outer membrane of eukaryotic cells and are named for their catalytic subunit. The encoded protein is the catalytic subunit for PI3Kbeta (PI3KB). PI3KB has been shown to be part of the activation pathway in neutrophils which have bound immune complexes at sites of injury or infection. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2011]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit 30% fetal lethality, decreased size at birth and postnatally, abnormal glucose homeostasis, and dyslipidemia. Mice homozygous for a different knock-out allele die prior to E8.5 [provided by MGI curators]
