Background InformationPhosphoinositol-3-kinases (PI3 Kinase, PI3K) are a family of lipid kinases that mediate many intracellular signaling responses in both physiological and pathophysiological states. PI3 Kinase is a heteroduplex with three classes (I, II, & III) of catalytic domain. The class I PI3 Kinases are made up of a p85 regulatory protein and a p110 catalytic domain. There are 4 isoforms of the class I p110 catalytic domains. Class I(A) include α, β, γ and class I(B). They are activated downstream via receptor tyrosine kinases or G-protein coupled receptors. Once activated, PI3K generates phosphatidylinositol 3,4,5-trisphosphate (PIP3) from PIP2. It was later found that PTEN, a lipid phosphatase, acts opposite to PI3K by dephosphorylating PIP3, converting it to PIP2, thus de-activating the effects of PI3K. Increased levels of PIP3 in the cell leads to the activation of many key signaling regulators including Akt and PDK as well as calcium release. One of the primary roles of PI3K is its regulation of cell growth and cell metabolism. Both of these play a critical role in cancer as some believe that a tumor’s shift to glycolysis is due to the activation of PI3K. PI3 kinases have been linked with numerous disease states, including cancer, diabetes, allergic response, hypertension, cardiac contractility, atherosclerosis, sepsis and autoimmune/ inflammatory disorders.

Entrez Gene Number
Entrez Gene SummaryPhosphatidylinositol 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. [provided by RefSeq].

UniProt Number
UniProt SummaryFUNCTION: Phosphorylates PtdIns, PtdIns4P and PtdIns(4,5)P2 with a preference for PtdIns(4,5)P2.

CATALYTIC ACTIVITY: ATP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate = ADP + 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate.

SUBUNIT STRUCTURE: Heterodimer of a p110 (catalytic) and a p85 (regulatory) subunit. Binds to IRS1 in nuclear extracts. Interacts with RUFY3 By similarity.

INVOLVEMENT IN DISEASE: Defects in PIK3CA are associated with colorectal cancer (CRC) [MIM:114500].
Defects in PIK3CA are associated with breast cancer [MIM:114480].
Defects in PIK3CA are associated with ovarian cancer [MIM:167000]. Ovarian cancer is the leading cause of death from gynecologic malignancy. It is characterized by advanced presentation with loco-regional dissemination in the peritoneal cavity and the rare incidence of visceral metastases. These typical features relate to the biology of the disease, which is a principal determinant of outcome.
Defects in PIK3CA may underlie hepatocellular carcinoma (HCC) [MIM:114550]. Ref.14
PI3KCA mutations affecting exons 9 and 20 display gender- and tissue-specific patterns, thus suggesting that the different amino acid changes could exert distinct functional effects on the oncogenic properties of this enzyme. Furthermore, sexual dimorphisms and tissue specific factors might directly or indirectly influence the occurrence of PI3KCA cancer alleles.
