IRS1 binds mutated PIK3CA. 3 / 3
| 3

reach
"Interaction between the helical domain mutant p110alpha and IRS1 does not require p85 or IRS1 phosphorylation."

reach
"In support of earlier results, it was also notable that the stapled mutant peptide did slightly reduce the protein levels of p110alpha, but did not affect levels of p85 and IRS1 (XREF_FIG and XREF_SUPPLEMENTARY), providing further evidence that the protein interaction between mutant p110alpha and IRS1 stabilizes p110alpha."

reach
"We then tested if peptides corresponding to only one of the two alpha-helical motifs could inhibit interactions between the mutant p110alpha and IRS1."
