WebThe p53 protein directs suicide of cell with DNA damage. Normally the p53 protein helps the cell destroy itself (cell suicide, or apoptosis) when its DNA becomes damaged (top row). This prevents the cell from going on to divide. But if the p53 gene has a mutation, then the p53 protein doesn’t work properly to help the cell commit suicide.
