Analysis of mutant p53 for MAR-DNA binding: determining the dominant-oncogenic function of mutant p53
At least some mutant p53 proteins not s imply have los t the wild-type p53 specific tumor suppressor function, but exhibit oncogenic functions on their own. Recently we showed that binding of mutant p53 to MAR/SAR elements is an act ivity specif ic for mutant p53 and clearly distinguishable from the previously reported DNA-binding activities of p53. Since MAR/SAR elements are considered to be i...
متن کاملSer Phosphorylation Regulates the Oncogenic Function of Mutant p53
Despite the wealth of information on the regulation of wild-type p53 function by phosphorylation, nothing is known about the biological effect of phosphorylation on mutant p53. Here we show that p53H175 is phosphorylated like wild-type p53 in cells of the same background. Ser nonphosphorylatable p53 mutants p53H175A392 and p53W248A392 more potently transformed rat embryo fibroblasts in cooperat...

متن کاملTargeting Oncogenic Mutant p53 for Cancer Therapy
Among genetic alterations in human cancers, mutations in the tumor suppressor p53 gene are the most common, occurring in over 50% of human cancers. The majority of p53 mutations are missense mutations and result in the accumulation of dysfunctional p53 protein in tumors. These mutants frequently have oncogenic gain-of-function activities and exacerbate malignant properties of cancer cells, such...
متن کاملControl of Nucleotide Metabolism Enables Mutant p53’s Oncogenic Gain-of-Function Activity
Since its discovery as an oncoprotein in 1979, investigation into p53's many identities has completed a full circle and today it is inarguably the most extensively studied tumor suppressor (wild-type p53 form or WTp53) and oncogene (mutant p53 form or mtp53) in cancer research. After the p53 protein was declared "Molecule of the Year" by Science in 1993, the p53 field exploded and a plethora of...
