PIK3CA, one of the two most frequently mutated oncogenes in human tumors, codes for p110α, the catalytic subunit of a phosphatidylinositol 3-kinase, isoform α (PI3Kα, p110α/p85). Here, we report a 3.0 angstrom resolution structure of a complex between p110α and a polypeptide containing the p110α-binding domains of p85α, a protein required for its enzymatic activity. The structure shows that many of the mutations occur at residues lying at the interfaces between p110α and p85α or between the… Expand
