he MDMX protein also known as MDM4 is an important regulator in the control of the p53 tumor suppressor pathway. Typically MDMX can be found expressed in multiple tissue types including the brain and kidney. MDMX with a molecular mass of approximately 54 kDa functions as an E3 ligase that binds to the p53 protein inhibiting its transcriptional activity and promoting its degradation. This precise interaction with p53 allows the regulation of cell growth and apoptosis making MDMX an important target for cancer research./ Biological function summary/ MDMX contributes significantly to cell cycle regulation and apoptosis by forming a complex with MDM2 another E3 ubiquitin ligase. Together with MDM2 MDMX modulates the stability and activity of p53 therefore influencing cell fate decisions. This complex is important in preventing unwarranted p53 activity ensuring that the cell only undergoes apoptosis or cell cycle arrest in response to specific stress signals./
