The key protein involved in "deciding" whether a cell with DNA damage should delay its cell cycle or undergo apoptosis is

Question

Quizplus · Accepted Answer

p53 is a tumor suppressor protein that plays a critical role in regulating the cell cycle and DNA damage response. When a cell with DNA damage is unable to repair the damage, p53 is activated and triggers the decision-making process of whether the cell should delay its cell cycle to give time for repair or undergo apoptosis to prevent passing on the mutated DNA to daughter cells. Akt, pRB, and p15 are also involved in cell cycle regulation, but they are not the key proteins involved in the decision-making process of DNA damage response.
