Comparative 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 کاملActivation of p53 Sequence-Specific DNA Binding by Acetylation of the p53 C-Terminal Domain
The tumor suppressor p53 exerts antiproliferation effects through its ability to function as a sequence-specific DNA-binding transcription factor. Here, we demonstrate that p53 can be modified by acetylation both in vivo and in vitro. Remarkably, the site of p53 that is acetylated by its coactivator, p300, resides in a C-terminal domain known to be critical for the regulation of p53 DNA binding...
متن کامل14-3-3 activation of DNA binding of p53 by enhancing its association into tetramers
Activation of the tumour suppressor p53 on DNA damage involves post-translational modification by phosphorylation and acetylation. Phosphorylation of certain residues is critical for p53 stabilization and plays an important role in DNA-binding activity. The 14-3-3 family of proteins activates the DNA-binding affinity of p53 upon stress by binding to a site in its intrinsically disordered C-term...
متن کاملNovel FOXC2 Mutation in Hereditary Distichiasis Impairs DNA-Binding Activity and Transcriptional Activation
Distichiasis presents as double rows of eyelashes arising from aberrant differentiation of the meibomian glands of the eyelids, and it may be sporadic or hereditary. FOXC2 gene mutations in hereditary distichiasis are rarely reported. Here, we examined two generations of a Chinese family with hereditary distichiasis but without lymphedema or other features of LD syndrome. The FOXC2 gene was amp...
