On framework, and that this state of subcellular localization is important for IRS1/PI3K dependent mitogenic and metabolic actions [21,22]. In a search for scaffolding proteins that may provide a link between the actin cytoskeleton and localized IRS1/PI3K signaling we have identified nexilin, an F-actin binding protein which we show binds selectively to IRS1 but not …
