RAS GTPases are important mediators of oncogenesis in humans. However, pharmacological inhibition of RAS has proved challenging. Here, we describe a functionally critical region of RAS located outside the effector lobe that can be targeted for inhibition. We developed a synthetic binding protein (monobody), termed NS1, that bound with high affinity to both GTP- and GDP-bound states of H- and K-RAS but not N-RAS. NS1 potently inhibited growth factor signaling and oncogenic H- and K-RAS-mediated signaling and transformation but did not block oncogenic N-RAS, BRAF or MEK1. NS1 bound the α4-β6-α5 region of RAS disrupting RAS dimerization/nanoclustering, which in turn blocked CRAF:BRAF heterodimerization and activation. These results establish the importance of the α4-β6-α5 interface in RAS-mediated signaling and define a previously unrecognized site in RAS for inhibiting RAS function.
