p53 (protein)

p53 is a crucial protein in the body that helps protect against cancer. It acts as a "guardian of the genome" by monitoring cell DNA for damage. When p53 detects genetic errors, it can stop cell growth, repair the DNA, or trigger cell death if the damage is too severe. This process prevents damaged cells from becoming cancerous. Mutations or loss of p53 function are common in many cancers, making it a key target for cancer research and treatments. Essentially, p53 helps maintain healthy cells and prevents tumor development.
