Role of Rho, Rac, and Rho-kinase in phosphorylation of myosin light chain, development of polarity, and spontaneous migration of Walker 256 carcinosarcoma cells

Our findings suggest an important role of Rac, Rho/Rho-kinase, and MLCK in controlling myosin activity in Walker carcinosarcoma cells and show that an appropriate level of RhoA, Rac, and Rho-kinase activity is required to regulate cell polarity and migration.
