Answer:
relaying a signal from a growth factor receptor
Explanation:
Mutation of an income changes the function of the encoded protein, creating the malignant properties that are needed for cancer to grow and spread.
Cancer-causing mutation of Ras creates a form of the protein that is always on.
Ras proteins function as binary molecular switches that control intracellular signaling networks. Ras-regulated signal pathways control such processes as actin cytoskeletal integrity, cell proliferation, cell differentiation, cell adhesion, apoptosis, and cell migration.
