C-Raf (Raf1) is one of the isoforms of Raf serine/threonine kinase. The others are A-Raf and B-Raf. The Raf-kinase is activated by Ras protein. Activated Raf will trigger the phosphorylation of MEK and ERK, which regulates some transcription factors that induce gene expression required for cell proliferation. Raf1 activation is found in 50% of renal cell carcinoma and 100% of hepatocellular carcinoma (Scott Wilhelm et al., 2006). Sorafenib is an FDA approval small molecule for Raf1 inhibitor. Sorafenib also binds to B-Raf.
