The p53 protein consists of the N-terminal transactivation, the DNA binding or core, the tetramerization, and the C-terminal regulatory domain (Figure 3). This Proteopedia page discusses protein-DNA recognition by p53, thus focuses on the DBD of p53. The only other domain for which structural information is available is the <scene name='Sandbox_Reserved_170/Tetra/1'>tetramerization domain</scene>, which forms as a dimer of dimers with one alpha helix and one beta strand contributed by each p53 monomer.
