p53 mutations isolated in yeast based on loss of transcription factor activity: similarities and differences from p53 mutations detected in human tumors.

Abstract excerpt

p53 is a transcriptional activator that plays a key role in the integration of signals inducing cell division arrest and programmed cell death. Moreover, p53 is a tumor suppressor gene, mutations of which are the most commonly detected mutations in diverse malignancies. In order to better understand the significance of p53 mutations to human cancer, we isolated mutant alleles of p53 that had lost transcription...
