What happens if a G 1 cell sustains genetic damage?

When a cell sustains genetic damage, the p53 protein concentration rises due to an increase in the stability of the p53 protein, not necessarily because of increased expression of the p53 gene. This mechanism allows the cell to halt the cell cycle and attempt repair, highlighting the role of p53 as a tumor suppressor and guardian of the genome.
