MDM4/MDMX proteins cooperate with MDM2 to regulate TP53 (p53) and inhibit the transcriptional activation domains of p53 and p73. This hinders their ability to induce cell cycle arrest and apoptosis. MDM4/MDMX Protein, Human (His) is the recombinant human-derived MDM4/MDMX protein, expressed by E. coli , with N-His labeled tag.
