Abstract

Ras proteins function as binary switches cycling between inactive GDP-and active GTP-bound forms. These proteins transduce signals from cell surface receptors into the cytoplasm via specific effector pathways and have achieved notoriety as oncogenes. Oncogenic Ras proteins, which are locked in the active state as a result of being insensitive to inactivation catalysed by Ras GTPase-activating proteins (RasGAPs), are constitutively active in transforming mammalian cells (20 per cent of human tumours contain activating Ras mutations). Here we address how the ubiquitious phosphoinositide regulated RasGAPs, GAP1IP4BP and GAP1m, coordinate the regulation of Ras GTPases during receptor activation.
