The p85alpha nSH2 does not contact the lipid binding elements in the kinase C-lobe (Figure 4a) but appears to control their access to membrane (Figure 3f-j). This suggests the activation mechanism by nSH2 to be allosteri
[Paragraph-level] PMCID: PMC3378484 Section: RESULTS PassageIndex: 22
Evidence Type(s): Functional, Oncogenic
Justification: Functional: The passage discusses how the H1047R variant leads to a global conformational change in the p110alpha/p85alpha structure, suggesting that it alters molecular function and potentially impacts activity. Oncogenic: The context implies that the H1047R variant contributes to tumor development or progression through its role in altering the conformational dynamics of the kinase, which is relevant in cancer biology.
