MEK inhibitor RO4987655 binds to and inhibits MEK, which may result in the inhibition of MEK-dependent cell signaling and the inhibition of tumor cell proliferation. MEK, a dual specificity threonine/tyrosine kinase, is a key component of the RAS/RAF/MEK/ERK signaling pathway that regulates cell growth; constitutive activation of this pathway has been implicated in many cancers."}]
