Binding of MAR-DNA elements by mutant p53: possible implications for its oncogenic functions.

Abstract excerpt

The tumor suppressor p53 is a multifunctional protein whose main duty is to preserve the integrity of the genome. This function of wild-type p53 as "guardian of the genome" is achieved at different levels, as a cell cycle checkpoint protein, halting the cell cycle upon DNA damage, and via a direct involvement in processes of DNA repair. Alternatively, p53 can induce apoptosis. Mutations in the p53 gene occur in...
