Ras is a small protein that functions in many signaling pathways. In its active form, with GTP bound, Ras transmits a signal that leads to cell proliferation. In its inactive form, with GDP bound, the signal is not transmitted. Mutations in the gene for Ras are found in many cancers. Which type of mutation in Ras is MOST likely to contribute to uncontrolled cell growth?
