PI3K (Phosphoinositide 3-kinase), via phosphorylation of the inositol lipid phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), forms the second messenger molecule phosphatidylinositol (3,4,5)-trisphosphate (PI(3,4,5)P3) which recruits and activates pleckstrin homology domain containing proteins, leading to downstream signalling events crucial for proliferation, survival and migration. The four distinct catalytic isoforms of class I PI3K enzymes are PI3K, PI3K, PI3K, and PI3K.
Three main classes of PI3K enzymes exist, with class IA being strongly linked to cancer. Catalytic subunits (p110α, p110β, or p110δ; encoded by PIK3CA, PIK3CB, and PIK3CD genes, respectively) and regulatory subunits (p85) make up heterodimeric lipid kinases known as class IA PI3K.
The PI3K pathway is crucial for the progression of the cell cycle, cell growth and survival, actin rearrangement and migration, and intracellular vesicular transport, among many other biological processes.
