Which of the following is considered a proto-oncogene?

Question

Quizplus · Accepted Answer

All of these choices are considered proto-oncogenes because mutations in any of these genes can lead to uncontrolled cell growth and ultimately cancer. For example, a mutation in a cell-surface receptor gene could lead to overactive signaling pathways that promote cell growth, while a mutation in a growth factor gene could result in excessive production of that growth factor, also promoting cell growth. Similarly, mutations in genes encoding protein kinases or G-proteins can disrupt normal signaling pathways and contribute to tumorigenesis.
