Posttranslational modifications are essential for regulating the transcription factor p53, which binds DNA in a highly cooperative manner to control expression of a plethora of tumor-suppressive programs. Here we show at the biochemical, cellular, and organismal level that the cooperative nature of DNA binding is reduced by phosphorylation of highly conserved serine residues (human S183/S185, mouse S18 in the DNA-binding domain. To explore the role of this inhibitory phosphorylation in vivo, new phosphorylation-deficient p53-S
