PIK3CA encoding the phosphoinositide 3-kinase (PI3K) p110alpha catalytic subunit is frequently mutated in cancer, with mutations occurring widely throughout the primary sequence. The full set of mechanisms underlying how
[Paragraph-level] PMCID: PMC9837058 Section: ABSTRACT PassageIndex: 1
Evidence Type(s): Oncogenic, Functional
Justification: Oncogenic: The passage discusses how mutations in PIK3CA, including G1049R, H1047R, and M1043I/L, contribute to the activation of the PI3K pathway, indicating their role in tumor development or progression. Functional: The passage describes how specific mutations alter the conformation and binding properties of the p110alpha subunit, indicating that these variants affect molecular function related to PI3K activation.
