WebbNormally, wild-type p53 protein (wtp53) is either degraded or bound to a negative regulator and is inactive. When damage to DNA occurs within a cell, p53 protein is induced and causes cell cycle arrest. This gives cells a chance to repair, but if damage is too severe, cells undergo apoptosis and are rejected. WebbThe mutant p53 proteins examined so far each have a much longer half-life than that of the wild-type p53 protein which is rapidly degraded under normal conditions.
