Tumour suppressor protein p53 and DNA. Molecular model of a tumour suppressor p53 (magenta, green, purple, orange) bound to two spiral strands of DNA (deoxyribonucleic acid, red and green, blue and light-blue) genetic material. Tumour suppressor p53 is a protein that binds to a specific DNA gene sequence that regulates the cell cycle and p53 blocks this sequence and is thus involved in preventing cancer.
