PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha) is a gene that encodes the protein phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform, a subunit of the PI3K protein. Phosphatidyl 3-kinases (PI3K) are a family of lipid kinases involved in many cellular processes, including cell growth, proliferation, differentiation, motility, and survival. Mutant PIK3CA has been implicated in the pathogenesis of several cancers, including colon cancer, glioma, gastric cancer, breast cancer, endometrial cancer, and lung cancer (COSMIC; PMID: 15016963).
