[https://www.uniprot.org/uniprot/MDM2_HUMAN MDM2_HUMAN] E3 ubiquitin-protein ligase that mediates ubiquitination of p53/TP53, leading to its degradation by the proteasome. Inhibits p53/TP53- and p73/TP73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Also acts as an ubiquitin ligase E3 toward itself and ARRB1. Permits the nuclear export of p53/TP53. Promotes proteasome-dependent ubiquitin-independent degradation of retinoblastoma RB1 protein. Inhibits DAXX-mediated apoptosis by inducing its ubiquitination and degradation. Component of the TRIM28/KAP1-MDM2-p53/TP53 complex involved in stabilizing p53/TP53. Also component of the TRIM28/KAP1-ERBB4-MDM2 complex which links growth factor and DNA damage response pathways. Mediates ubiquitination and subsequent proteasome degradation of DYRK2 in nucleus.

Restoration of p53 function through the disruption of the MDM2-p53 protein complex is a promising strategy for the treatment of various types of cancer. Here, we present kinetic, thermodynamic, and structural rationale for the remarkable potency of a new class of MDM2 inhibitors, the piperidinones. While these compounds bind to the same site as previously reported for small molecule inhibitors, such as the Nutlins, data presented here demonstrate that the piperidinones also engage the N-terminal region (residues 10-16) of human MDM2, in particular, Val14 and Thr16. This portion of MDM2 is unstructured in both the apo form of the protein and in MDM2 complexes with p53 or Nutlin, but adopts a novel beta-strand structure when complexed with the piperidinones. The ordering of the N-terminus upon binding of the piperidinones extends the current model of MDM2-p53 interaction and provides a new route to rational design of superior inhibitors.
