g., phosphorylation and acetylation) and DNA binding cooperativity of p53. In this issue of Cancer Research, Timofeev and colleagues show that a previously uncharacterized phosphorylation in the p53 core DNA-binding domain regulates the DNA binding cooperativity and transcriptional activity of p53. Their mice deficient for this p53 phosphorylation were resistant to spontaneous and induced tumorigenesis, while they had shortened lifespan, but did not show progeria-like phenotypes. Prompted by this study, res
