Growth of normal cells is anchorage dependent because signalling through multiple pathways including Erk, phosphatidylinositol-3-OH kinase (PI(3)K) and Rac requires integrin-mediated cell adhesion. Components of these pathways localize to low-density, cholesterol-rich domains in the plasma membrane named 'lipid rafts' or 'cholesterol-enriched membrane microdomains' (CEMM).
