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.
