P53 protein domain structure. The N-terminal part amino acids 1–42, constitutes the transactivation domain. The proline-rich domain, from amino acid 42 to amino acid 100, is proven necessary for p53 dependent apoptosis and cell cycle arrest. The DBD (DNA binding domain) is rich in arginine and related to transcriptional activity. The protein domain from amino acid 305 to amino acid 322 includes the nuclear localization domain. The domain from amino acid 340 to amino acid 351 includes the nuclear exclusion domain. In addition, the protein domain from amino acid 326 to amino acid 356 corresponds to the tetramerization domain. The C-terminal domain from amino acid 364 to amino acid 393 is required for DNA binding capability and DNA damage response
