... incompletely understood. To identify the specific intracellular molecules involved in CD148 signalling, we carried out a modified yeast two-hybrid screening assay. Using the substrate-trapping mutant form of CD148 (CD148 D/A) as bait, we recovered the p85 regulatory subunit of PI3K (phosphoinositide 3-kinase...

... insulin receptor substrates and its downstream binding proteins including p85 regulatory subunit of phosphoinositide 3-kinase and Grb2 (growth factor receptor-bound protein 2). The inhibitory effect of resveratrol on insulin signalling is also demonstrated at mRNA level, where resveratrol reverses insulin...

... showed that Gα q competes with Ras, a PI3K activator, for binding to p110α/p85α. Interestingly, co-precipitation studies using deletion mutants showed that Gα q binds to the p85-binding domain of p110α and not to the Ras-binding domain. Expression of constitutively active Gα q Q209L in cells inhibited...

... in areas of high substrate density such as membrane lipid rafts. We also compared protein-kinase activities. We found that p110β phosphorylated p85 to a lower degree than did p110α. We used a novel peptide-based assay to compare the kinetics of the protein-kinase activities of p110α and p110β. These...
