WebThe mechanism of PI3Kα activation that we determined underscores the action of the RTK motif via its interaction with the nSH2 and the associated large conformational change. The release of nSH2 permits the C-lobe of the kinase domain to get away from the C2 domain, priming PI3Kα for phosphorylation of the PIP 2 lipid substrate to PIP 3 ( 15, 56 ). WebThe phosphoinositide 3-kinase pathway is perhaps the most commonly activated signaling pathway in human cancer. This pathway thus presents both an opportunity and a challenge for cancer therapy. Even as inhibitors that choose PI3K isoforms and other leading nodes in the pathway including AKT and mTOR reach clinical trials, primary issues persist.
