abstract：:The p53 tumor suppressor gene product is a sequence-specific DNA-binding protein that is necessary for the G1 arrest of many cell types. Consistent with its role as a cell cycle checkpoint factor, p53 has been shown to be capable of both transcriptional activation and repression. Here we show a new potential role for ...
