Cancer-derived C-terminus-extended p53 mutation confers dominant-negative effect on its wild-type counterpart.

Abstract excerpt

The vast majority of p53 missense mutants lose the wild-type (wt) function and/or exert 'dominant-negative' effects on their wt counterpart. Here, we identify a novel form of p53 mutation with an extended C-terminus (p53 long C-terminus, p53LC) in a variety of human cancers. Interestingly, the two representative mutants (named 'p53-374*48' and 'p53-393*78') as tested in this study show both loss-of-function and...
