...es the cancer gene, or oncogene, called ras, which launches uncontrolled growth. In the Proceedings paper, Gishizky, Cortez and Pendergast reported discovering that a purposely "damaged" form of GRB-2 could suppress activation of ras and reverse the cancerous growth of human leukemia cells in test tubes.

This molecule launches a cascade of metabolic signals into the cell when it is produced by activation of receptors such as the "G-protein-coupled receptors" (GPCRs) studied by Lefkowitz's laboratory.
