NCIt definition : An orally available inhibitor of all members of the serine/threonine protein kinase
Raf family, including A-Raf, B-Raf and C-Raf protein kinases, with potential antineoplastic
activity. Upon administration, pan-RAF kinase inhibitor LY3009120 inhibits Raf-mediated
signal transduction pathways, which may inhibit tumor cell growth. Raf protein kinases
play a key role in the RAF/mitogen-activated protein kinase kinase (MEK)/extracellular
signal-regulated kinase (ERK) signaling pathway, which is often dysregulated in human
cancers and plays a key role in tumor cell proliferation and survival.;
