  • 产品描述：

    The process of expressing the recombinant mouse Mdm2 protein in the E.coli requires the recombinant DNA gene formed by the integration of encoding gene for the 1-489aa of the mouse Mdm2 protein and N-terminal 6xHis tag sequence, the expression vector that the recombinant DNA gene inserts into, the E.coli that provided the necessary macromolecules and components for transcription and translation of the cloned expression vector. After isolation and purification, this N-terminal 6xHis-tagged recombinant Mdm2 protein was obtained. This recombinant Mdm2 protein is characterized by high purity (>90%, SDS-PAGE). This Mdm2 protein ran along the gel to the band of approximately 58 kDa molecular weight.

    E3 ubiquitin-protein ligase Mdm2 is a protein encoding by a gene named Mdm2 in mouse and a gene named MDM2 in human. Generally, MDM2 is known as a negative regulator of the tumour suppressor p53, making it an attractive target for anti-cancer drug design. Mdm2 affects p53 stability from two sections, one is  as an E3 ubiquitin ligase that recognizes the N-terminal trans-activation domain of the p53 tumor suppressor, another is as an inhibitor of p53 transcriptional activation. Currently, diseases involved MDM2 include Lessel-Kubisch Syndrome and Accelerated Tumor Formation.

  • 功能：
    E3 ubiquitin-protein ligase that mediates ubiquitination of p53/TP53, leading to its degradation by the proteasome. Inhibits p53/TP53- and p73/TP73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Also acts as a ubiquitin ligase E3 toward itself, ARRB1 and ARBB2. Permits the nuclear export of p53/TP53. Promotes proteasome-dependent ubiquitin-independent degradation of retinoblastoma RB1 protein. Inhibits DAXX-mediated apoptosis by inducing its ubiquitination and degradation. Component of the TRIM28/KAP1-MDM2-p53/TP53 complex involved in stabilizing p53/TP53. Also component of the TRIM28/KAP1-ERBB4-MDM2 complex which links growth factor and DNA damage response pathways. Mediates ubiquitination and subsequent proteasome degradation of DYRK2 in nucleus. Ubiquitinates IGF1R and SNAI1 and promotes them to proteasomal degradation. Ubiquitinates DCX, leading to DCX degradation and reduction of the dendritic spine density of olfactory bulb granule cells. Ubiquitinates DLG4, leading to proteasomal degradation of DLG4 which is required for AMPA receptor endocytosis. Negatively regulates NDUFS1, leading to decreased mitochondrial respiration, marked oxidative stress, and commitment to the mitochondrial pathway of apoptosis. Binds NDUFS1 leading to its cytosolic retention rather than mitochondrial localization resulting in decreased supercomplex assembly (interactions between complex I and complex III), decreased complex I activity, ROS production, and apoptosis.

    1. The proximal p53 inhibitor MDM2 is markedly downregulated in subcutaneous white and brown adipose tissues of mice during aging. Genetic disruption of MDM2 in adipocytes triggers canonical p53-mediated apoptotic and senescent programs, leading to age-dependent lipodystrophy and its associated metabolic disorders, including type 2 diabetes, nonalcoholic fatty liver disease, hyperlipidemia, and energy imbalance. PMID: 30131393
    2. To investigate whether MDM2C462A, which retains p53 binding, has p53-suppressing activity, we generated Mdm2C462A/C462A;p53ER/- mice. Adult Mdm2-null mice died approximately 7 days after tamoxifen-induced p53 activation, indicating that in the absence of MDM2, MDMX cannot suppress p53. p53 activity is higher in the presence of MDM2C462A than in the absence of MDM2.

In Fmr1 KO neurons, Mdm2 is hyperphosphorylated, nuclear localized basally, and unaffected by MEF2 activation, which our data suggest due to an enhanced interaction with Eukaryotic Elongation Factor 1alpha (EF1alpha), whose protein levels are elevated in Fmr1 KO.
