Reversible palmitoylation controls the localization and signaling of Ras. Development of a potent and specific small molecule inhibitor of the thioesterase APT1 reveals that this enzyme depalmitoylates Ras in cells. Inhibition of APT1 led to redistribution and altered activity of HRas, NRas and an oncogenic mutant Ras.
