[Dominant negative activity of mutated p53 proteins].

Abstract excerpt

Tumor suppressor gene inactivation as proposed by the Knudson model implies a sequential inactivation of two alleles of a gene. For example, the first allele is inactivated by a missense mutation, and the second one is inactivated by a deletion or insertion. The alteration of the p53 tumor suppressor gene is far to correspond only to this model. In the great majority of cancers, the mutated allele of p53 coexists...
