Immunoprecipitation of Human MDM2. U2OS human osteosarcoma cell line was untreated (-) or treated (+) with proteasome inhibitor LLnV for 1 hour. MDM2 was immunoprecipitated from 500 μg of cell lysate following incubation with 2‑3 µg Mouse Anti-Human MDM2 Monoclonal Antibody (Catalog # MAB1244) for 1 hour on ice. MDM2-antibody complexes were absorbed using goat anti-mouse agarose (Sigma). Immunoprecipitated MDM2 was detected by Western blot using 1 µg/mL Human/Mouse/Rat MDM2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1244).

MDM2 is a key regulator of p53 tumor suppressor protein activity and stability. MDM2 binds to and inhibits the transactivation domain of p53. In addition, MDM2 controls p53 stability by functioning as its E3 ligase in ubiquitination and by shuttling p53 from the nucleus to the cytoplasm for subsequent degradation. The importance of the p53/MDM2 relationship is underscored by the existence of an autoregulatory feedback loop whereby activated p53 transcriptionally upregulates the expression of its own inhibitor, MDM2.
