title: Cytoskeleton cross-talk during cell motility.
abstract: Cell crawling entails the co-ordinated creation and turnover of substrate contact sites that interface with the actin cytoskeleton. The initiation and maturation of contact sites involves signalling via the Rho family of small G proteins, whereas their turnover is under the additional influence of the microtubule cytoskeleton. By exerting relaxing effects on substrate contact assemblies in a site- and dose-specific manner, microtubules can promote both protrusion at the front and retraction at the rear, and thereby control cell polarity.
