Gα(q) binds to p110α/p85α phosphoinositide 3-kinase and displaces Ras

Several studies have reported that activation of G(q)-coupled receptors inhibits PI3K (phosphoinositide 3-kinase) signalling. In the present study, we used purified proteins to demonstrate that Gα(q) directly inhibits p110α/p85α PI3K in a GTP-dependent manner. Activated Gα(q) binds to the p110α/p85α...
