Biochem/physiol Actions

p110α (PIK3CA)/p85α (PIK3R1) isoform of phosphoinositide 3-kinase (PI3K), plays a critical role in the regulation of various cellular processes. These include cellular survival, proliferation, migration, invasion, and metastasis. Additionally, the signaling pathway involving the p110α isoform of PI3K is responsible for triggering physiological cardiac hypertrophy induced by exercise. PIK3 also plays a vital role in activating Protein kinase B or Akt (PKB/Akt), an essential component of insulin and growth factors signaling pathways. Furthermore, PIK3 participates in synthesizing PIP3 (phosphatidylinositol (3,4,5)-trisphosphate), a key signaling molecule within the PI3K/Akt pathway. These significant functions highlight the critical role of PIK3 in mediating important cellular signaling processes, including inositol phosphate metabolism. PIK3CA mutations can alter the tumor immunogenicity, which potentially affects its susceptibility to immunotherapies. The E545K substitution is a somatic mutation in p110α that has been associated with tumors of the colon and brain. Combined in vitro and in vivo studies have shown that this mutation confers higher lipid kinase activity than the wild type and is able to induce oncogenic transformation.
