Oncogenic Mutants of MEK1: A Trilogy Unfolds

Cancer Discov. 2018 May;8(5):534-536. doi: 10.1158/2159-8290.CD-18-0192.

Abstract

<b/> It has generally been assumed that MEK mutants function similarly to one another and respond in the same manner to targeted drugs. Gao and colleagues challenge this assumption and report that MEK1 mutants fall into three unique phenotypic classes with respect to RAF dependency. A new class of MEK1 mutants is shown here to be RAF-independent, resistant to allosteric MEK inhibitors, and yet sensitive to treatment with a new ATP-competitive MEK inhibitor.
