Crystal structure of human MDMX in complex with a 12-mer peptide inhibitor

Template:ABSTRACT PUBMED 19255450

Function

[MDM4_HUMAN] Inhibits p53/TP53- and TP73/p73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Inhibits degradation of MDM2. Can reverse MDM2-targeted degradation of TP53 while maintaining suppression of TP53 transactivation and apoptotic functions.[1] [2]
