Protein p53: Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control cell proliferation. A mutant or absent p53 protein has been found in leukemia, osteosarcoma, lung cancer, and colorectal cancer.

Synonym: antioncogene protein p53, human tp53 protein, tp53 protein, protein tp53, phosphoprotein pp53, oncoprotein p53.
