Brother's Keeper: Wild-Type Mutant K-Ras Dimers Limit Oncogenesis.

ABSTRACT

K-Ras is the undisputed champion of oncogenes, yet our ability to interfere with its oncogenic function is hampered by insufficient mechanistic understanding. In this issue of Cell, Ambrogio and colleagues connect the ability of K-Ras to dimerize to the ability of wild-type K-Ras to limit the oncogenic properties of the mutant.
