Function

MDM2_XENLA E3 ubiquitin-protein ligase that mediates ubiquitination of p53/TP53, leading to its degration by the proteasome (By similarity).

Publication Abstract from PubMed

Restoration of p53 activity by inhibition of the p53-MDM2 interaction has been considered an attractive approach for cancer treatment. However, the hydrophobic protein-protein interaction surface represents a significant challenge for the development of small-molecule inhibitors with desirable pharmacological profiles. RG7112 was the first small-molecule p53-MDM2 inhibitor in clinical development. Here, we report the discovery and characterization of a second generation clinical MDM2 inhibitor, RG7388, with superior potency and selectivity.
