Abstract

The tumour suppressor gene p53 is frequently mutated in human cancer. Tumour derived p53 mutants are usually transcriptionally inactive, but some mutants retain the ability to transactivate a subset of p53 target genes. In addition to simple loss of function, some p53 mutants may be carcinogenic through a dominant negative mechanism. Aiming at a more general classification of p53 mutants into predictive functional categories it is important to determine (i) which p53 mutants are dominant, (ii) what features characterize dominant mutants and (iii) whether dominance is target gene specific. The ability of 71 p53 mutants to inhibit wild type p53 was determined using a simple yeast transcriptional assay. Approximately 30% of the mutants were dominant. They preferentially affect highly conserved amino acids (P
