Abstract
The PI3K (phosphoinositide 3-kinase) p110α isoform is activated by oncogenic mutations in many cancers. This has stimulated intense interest in identifying inhibitors of the PI3K pathway as well as p110α-selective inhibitors, and understanding the mechanisms underlying activation by the oncogenic mutations. In the present article, we review recent progress in the structure and function of the p110α enzyme and two of its most common oncogenic mutations, the development of isoform-selective inhibitors, and p110α pharmacology.
