Cancer Discov, 13:56-69, 2023 Cited by PubMed Abstract: The transcription factor and tumor suppressor protein p53 is the most frequently mutated and inactivated gene in cancer. Mutations in p53 result in deregulated cell proliferation and genomic instability, both hallmarks of cancer. There are currently no therapies available that directly target mutant p53 to rescue wild-type function. In this study, we identify covalent compsounds that selectively react with the p53 somatic mutant cysteine Y220C and restore wild-type thermal stability.
