Textbook Question
Chapter 10, Problem 3VCQ
Figure 10.14 Human papillomavirus can cause cervical cancer. The virus encodes E6, a protein that binds p53. Based on this fact and what you know about p53, what effect do you think E6 binding has on p53 activity?
- E6 activates p53
- E6 inactivates p53
- E6 mutates p53
- E6 binding marks p53 for degradation

Retroviruses can cause cancer, along with some viruses with DNA genomes. For example, herpes papillomavirus causes cervical cancer. The HPV genome encodes a protein called E6 that interferes with p53 function, and another protein called E7 that inhibits the function of Rb protein.
Explain how HPV causes cancer. Are the viral E6 and E7 protein functions more similar to oncogenes or tumor suppressors?

- Some studies have pointed that mutant p53 proteins have gained a novel function by inactivating p63/p73. Can you elaborate about this - thanksarrow_forwardA 42-year-old woman comes to the physician for a follow-up examination after two separate Pap smears have shown dysplastic epithelial cells. Results of a molecular diagnostic test show DNA that encodes high-risk versions of the human papillomavirus E6 and E7 proteins. The viral E6 protein binds to the cellular p53 tumor suppressor gene, causing it to be degraded. Which of the following best describes the mechanism by which the E6 protein causes cervical cancer? (A) Arrests the cell cycle (B) Enhances tissue invasion and metastasis (C) Inhibits telomerase expression (D) Prevents apoptosis (E) Sustains angiogenesisarrow_forwardWhich of the following could be classified as an oncogene?

This hypothesis may also explain why p63 is associated with other indications of misinterpretation.
