Our results rather suggest that Mdm2 specifically ubiquitinates NUB1 on lysine 159 and that this modification is required for NUB1 functions.|We conclude that Mdm2 acts as a positive regulator of NUB1 function, by modulating NUB1 ubiquitination on lysine 159. |

Here, we demonstrate that overexpression of RFP2 in cells induced apoptosis through proteasomal degradation of MDM2 and AKT. We observed that RFP2 formed a complex with MDM2, a negative regulator of the p53 tumor suppressor, and AKT, a regulator of apoptosis inhibition at the cellular level. Additionally, we found that the interaction of RFP2 with MDM2 and AKT resulted in ubiquitination and proteasomal degradation of MDM2 and AKT in vivo and in vitro. |

Our current results demonstrated that the binding of Mdm2 to beta-arrestin 2 was significantly enhanced by stimulation of GPCRs. Activation of GPCRs led to formation of a ternary complex of Mdm2, beta-arrestin 2, and GPCRs and thus recruited Mdm2 to GPCRs at plasma membrane. Moreover, the binding of beta-arrestin 2 to Mdm2 suppressed the self-ubiquitination of Mdm2 and consequently reduced the Mdm2-mediated p53 degradation and ubiquitination. |

Here, we show that IFIXalpha1 downregulates HDM2, a principal negative regulator of p53, at the posttranslational level. IFIXalpha1 destabilizes HDM2 protein and promotes its ubiquitination. The E3 ligase activity of HDM2 appears to be required for this IFIXalpha1 effect. Importantly, HDM2 downregulation is required for the IFIXalpha1-mediated increase of p53 protein levels, transcriptional activity, and nuclear localization, suggesting that IFIXalpha1 positively regulates p53 by acting as a negative regulator of HDM2. |
