Oncogene: All mammalian cells express 3 related Ras proteins, termed H-Ras, K-Ras, and N-Ras, that promote oncogenesis when they are mutationally activated. K-Ras mutations are frequently observed in cancer, and each isoform displays preferential coupling to particular cancer types. Mutations of the K-Ras gene occur in over 90% of pancreatic carcinomas.
