Abstract
Decades of research reveal that MDM2 participates in cellular processes ranging from macro-molecular metabolism to cancer signaling mechanisms. Two recent studies uncovered a new role for MDM2 in mitochondrial bioenergetics. Through the negative regulation of NDUFS1 (NADH:ubiquinone oxidoreductase 75 kDa Fe-S protein 1) and MT-ND6 (NADH dehydrogenase 6), MDM2 decreases the function and efficiency of Complex I (CI). These observations propose several important questions: (1) Where does MDM2 affect CI activity? (2) What are the cellular consequences of MDM2-mediated regulation of CI? (3) What are the physiological implications of these interactions? Here, we will address these questions and position these observations within the MDM2 literature.
