| Gene Variant Descriptions | TP53 I255F lies within the DNA-binding domain of the Tp53 protein (PMID: 15510160). I255F retains interaction with PPTG1-binding factor in culture (PMID: 25408419) but results in reduced transactivation activity compared to wild-type Tp53 in a reporter assay (PMID: 22710932), and therefore, is predicted to lead to a loss of Tp53 protein function. |
