The protein p53 is considered as the guardian angel of cell's gen- ome. It plays an important role at G1 check point in the regulation of cell division cycle. It guards the integrity of the DNA.
The protein is existing at lower density in the cell. When the protein remains present in higher concentration, the cell division is ceased and the cell faces apoptosis.
If there is some mutation which can be mended, the correction is implanted. Thus, the protein helps in the maintenance of the functional DNA within a normal cell.
