Mammals have 8 distinct isoforms of PI3K. One of the key PI3K isoforms in cancer is p110a, as this isoform is extremely frequently activated by mutation. How p110a achieves this function is not clear, and my main aim is to investigate the role and mechanism of action of p110a in an oncogenic context, to provide a comprehensive picture of the molecular events controlled by p110a, and to identify m ...
