The cascade comprising Raf, mitogen-activated protein kinase kinase (MEK) and extracellular signal-regulated kinase (ERK) is a therapeutic target in human cancers with deregulated Ras signalling, which includes tumours that have inactivated the Nf1 tumour suppressor. Nf1 encodes neurofibromin, a GTPase-activating protein that terminates Ras signalling by(More)
Oncogenic K-Ras proteins, such as K-Ras(G12D), accumulate in the active, guanosine triphosphate (GTP)-bound conformation and stimulate signaling through effector kinases. The presence of the K-Ras(G12D) oncoprotein at a similar abundance to that of endogenous wild-type K-Ras results in only minimal phosphorylation and activation of the canonical(More)
