Methods of modulating macropinocytosis in cells of a target cell population by modulating the binding of Pak1 to DLC1/PIN are disclosed. In addition, the invention provides for methods of screening for modulators of macropinocytosis that involve determining whether a candidate substance inhibits or promotes the binding of Pak1 to DLC1/PIN. Also disclosed are methods of reducing cell proliferation in a target cell population, methods of inhibiting growth and survival of a cancer cell, methods of inhibiting the invasiveness of a cancer cell, and methods of treating viral infection using an agent that modifies the binding of Pak1 to DLC1/PIN.
