Outline of Final Research Achievements |
p53 can preventDNA. the cancer of a living cell by binding to a part of DNA (target). In this study, we investigated the mechanism in which p53 searches and binds to the target and the role of disordered region of p53. We measured the movement of p53 along DNA. We found that p53 has a low target recognition probability(TRP) and regulates TRP by posttransmodifications of p53. Furhtermore, we found that elongation of the disordered region of p53 caused the loss of specific binding to DNA.
