p53: a transdominant regulator of transcription whose function is ablated by mutations occurring in human cancer.

Abstract excerpt

Gal4-p53 fusion constructs demonstrate that wild type p53 is a potent transactivator in human lung cancer cells with the transactivation domain for p53 residing in amino acids 1-42. Strikingly, a variety of lung cancer derived p53 mutations occurring outside this domain disrupt this activity. Temperature sensitive conformational shifts of p53 mutant proteins to the wild type form exist and, with a temperature...
