Flexible lid to the p53-binding domain of human Mdm2: implications for p53 regulation.
The stabilization of p53 against Mdm2-mediated degradation is an important event in DNA damage response. Initial models of p53 stabilization focused on posttranslational modification of p53 that would disrupt the p53-Mdm2 interaction. The N-terminal regions of both p53 and Mdm2 are modified in vivo in response to cellular stress, suggesting that modifications to Mdm2 also may affect the p53-Mdm...
متن کاملComparative Investigation of R213G Mutation in DNA-Binding Domain of P53 Protein via Molecular Dynamics Simulation
Introduction: P53 is a tumor suppressor protein with numerous missense mutations identified in its gene. These mutations are observed in a vast number of cancers. R213G is one of them which has a role in metastatic lung cancers. In this research, R213G was studied in comparison with the wild type via molecular dynamics simulation. Method: For the three-dimensional structure of the wild-type P53...

متن کاملAcetylation of the DNA binding domain regulates transcription-independent apoptosis by p53.
The tumor suppressor p53 induces apoptosis by altering the transcription of pro-apoptotic targets in the nucleus and by a direct, nontranscriptional role at the mitochondria. Although the post-translational modifications regulating nuclear apoptotic functions of p53 have been thoroughly characterized, little is known of how transcription-independent functions are controlled. We and others ident...
متن کاملMutational analysis of the p53 core domain L1 loop.
The p53 tumor suppressor gene acquires missense mutations in over 50% of human cancers, and most of these mutations occur within the central core DNA binding domain. One structurally defined region of the core, the L1 loop (residues 112-124), is a mutational "cold spot" in which relatively few tumor-derived mutations have been identified. To further understand the L1 loop, we subjected this reg...
