Summary

Cell movement is an elegant orchestration of different cellular processes that include microtubule dynamics, contraction of actin and myosin filaments, and the formation and turnover of integrin-rich adhesion complexes that serve as traction points over which the cell moves. In a comprehensive overview Perspective, Horwitz and Parsons discuss the mechanisms that regulate the dynamics of contractile forces and adhesion. New findings suggest the existence of a molecular `clutch' that regulates the balance of these processes ( Smilenov et al.).
