RAF inhibitors promote RAS-RAF interaction by allosterically disrupting RAF autoinhibition.

Abstract excerpt

First-generation RAF inhibitors paradoxically induce ERK signaling in normal and tumor cells exhibiting RAS activity. Compound-induced RAF dimerization through stabilization of the RAF ON/active state by inhibitors has emerged as a critical contributing factor. RAF inhibitors also enhance RAS-RAF association. Although this event is thought to play a key role in priming RAF activation, the underlying mechanism is...
