  • Raf genes are proto-oncogenes: they can initiate malignant transformation of cells when expressed in specifically altered forms. Genetic alterations leading to oncogenic activation produce a constitutively active protein kinase by removal or interference with an N-terminal negative regulatory domain of the protein (Heidecker, G., et al. (1990) Mol. Cell. Biol. 10: 2503-2512 Rapp, UR, et al., (1987), Oncogenes and Cancer; SA Aaronson, J. Bishop, T. Sugimura, M. Terada, K. Toyoshima, and P. K-Vogt (ed.) Japan
  • Raf-1 protein serine kinase is a candidate for "downstream" Effector of mitogen signal transduction, as Raf oncogenes encounter the growth arrest resulting from a blockade of cellular Ras activity due to a cellular mutation (Ras-revertant cells) or microinjection of anti-Ras antibodies (Rapp, UR, et al (1988) in The Oncogene Handbook, T. Curran, EP, Reddy and A. Skalka (eds), Elsevier Science Publishers, The Netherlands, pp. 213-253, Smith, MR, et al., (1986) Nature (London ) 320: 540-543).
