Model for SLK activation and recruitment at the leading edge. A proportion of SLK is microtubule-associated, likely through a microtubule-binding protein (X). Following activation of the FAK/c-Src complex, signaling through the MAPK pathway can activate and recruit the microtubule-SLK complex, inducing adhesion turnover by destabilization of the actin network or focal contacts/adhesions through an unknown mechanism. (C) denotes a cargo protein coupling the microtubule to polymerized actin. Nocodazole treatment fails to recruit SLK resulting in stable adhesions.
