The p53 gene is mutated in approximately half of all human cancers. It is involved in the cellular response to cytotoxic stresses, and together with p19ARF, induces expression of p21Cip1, to cause cell cycle arrest. In addition, p53 is able to induce apoptosis, both by transcriptional and non-transcriptional mechanisms. The amino-terminal 83 amino acids of p53 contain the transactivation domain, as well as the region involved in transcription-independent growth suppression. The carboxy-terminal region contains the DNA-binding domain, which is regulated by three phosphorylation events, and potentially by acetylation also.
