The p53 protein
WebbAs p53 likely functions as a tumor suppressor by regulating transcription, the ability of the E1B 19K protein to regulate p53-mediated transactivation and transcriptional repression … Webb8 aug. 2014 · p53 is stimulated when the DNA is damaged, and the gene triggers a series of responses that attempt to repair the affected DNA. The greater the damage inflicted upon the DNA, the more p53 is activated, and researchers have come to regard p53 levels as a marker of DNA distress. CRUCIFEROUS VEGETRABLES
