3D Print of Phosphoinositide 3-Kinase (PI3K) denoting common mutation sites (E545, H1047) that result in an oncogenic enzyme. This model was created from PDB dataset: 5DXT and visualizes the PI3K inhibitor GDC-0326.
PI3K are a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer. PI 3-kinases have been linked to an extraordinarily diverse group of cellular functions, including cell growth, proliferation, differentiation, motility, survival and intracellular trafficking. Many of these functions relate to the ability of class I PI 3-kinases to activate protein kinase B (PKB, aka Akt) as in the PI3K/AKT/mTOR pathway.
The p110δ and p110γ isoforms regulate different aspects of immune responses. PI 3-kinases are also a key component of the insulin signaling pathway. Hence there is great interest in the role of PI 3-kinase signaling in diabetes mellitus.
