We show that the specific subcellular distribution of H- and Nras guanosine triphosphate-binding proteins is generated by a constitutive de/reacylation cycle that operates on palmitoylated proteins, driving their rapid exchange between the plasma membrane (PM) and the Golgi apparatus. Depalmitoylation redistributes farnesylated Ras in all membranes,(More)
Dynamic assembly of spatially separated signaling platforms enables a cell to tune cellular outputs in response to different input stimuli. Understanding how a vast diversity in signaling responses can be generated from a limited protein repertoire requires knowledge of how cells maintain the segregation of proteins and thereby orchestrate their local(More)
