Although mutations in MAP2K proteins are infrequent in human cancers, the position of these kinases downstream of RAS and RAF make them good candidates for therapeutic targeting. Dual mechanism inhibitors such as trametinib bind to non-phosphorylated MAP2K proteins, inhibiting their MAPK-directed kinase activity as well as preventing their phosphorylation by RAF proteins (Hatzivassiliou et al, 2013; Lito et al, 2014; Ishii et al, 2013; reviewed in Samatar and Poulikakos, 2014).
