Ras is a member of the Ras superfamily of the G proteins, and it is a molecular switch which controls the transduction of signals from cell-surface receptors to intracellular targets. It was discovered in the 1980s when it was observed that 15% of all human tumors contain a point mutation in one of the three Ras proteins: H-Ras, K-Ras and N-Ras. Constantly active forms of these proteins can efficiently promote cell proliferation, thus leading to constant cell division and a broad spectrum of human tumors (2).
