p53 Peptides
Peptides derived from or targeting the p53 tumor suppressor pathway for cancer and senescence research.
Overview
p53 peptides encompass a class of synthetic peptides designed to modulate the p53 tumor suppressor pathway. p53 is mutated in over 50% of human cancers. Peptide-based approaches include reactivating mutant p53, stabilizing wild-type p53, and disrupting p53-MDM2 interactions.
The following information summarizes peer-reviewed research on p53 Peptides. Study descriptions reflect published findings, e.g., "animal studies have investigated," "cellular studies suggest," or "clinical trials have evaluated", and do not constitute therapeutic claims.
Mechanism of Action
Different p53 peptides work through distinct mechanisms: stapled peptides (e.g., ATSP-7041) bind MDM2/MDMX, preventing p53 degradation; reactivation peptides restore DNA-binding capacity of mutant p53; and transduction peptides deliver p53-derived sequences to trigger apoptosis in cancer cells.
