Protein: O15151

UniprotKB AC UniprotKB ID Gene name Full name Species Curated set
O15151 (Uniprot) MDM4_HUMAN MDM4 Protein Mdm4 human No
Uniprot: 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.
