Somatic missense mutations in PIK3CA, which encodes the p110alpha catalytic subunit of phosphoinositide 3-kinases (PI3Ks), occur frequently in human cancers. Activating mutations spread across multiple domains, some of w
[Paragraph-level] PMCID: PMC3378484 Section: ABSTRACT PassageIndex: 1
Evidence Type(s): Oncogenic, Functional
Justification: Oncogenic: The passage discusses somatic missense mutations in PIK3CA that contribute to increased kinase activities and lipid binding, indicating their role in tumor development or progression. Functional: The passage describes how specific mutations alter the molecular function of the p110alpha protein, including increased basal activity and lipid binding, which are indicative of changes in biochemical function.
