WebApr 19, 2024 · The p53 protein is a key transcription factor, and its activity is precisely regulated by the p53–MDM2 interaction. Although the p53–MDM2 interaction has been studied, it is still not clear how p53 structures and external factors influence the p53–MDM2 interaction in living cells. WebMdm2 protein controls the activity of p53 protein through working as ubiquitin E3 ligase promoting p53 degradation through the proteasome degradation pathway. Inhibitors for Mdm2-p53 interaction have restored the activity of p53 protein and induced cancer fighting properties in the cell.
