General description
MDM2 is an E3 ubiquitin ligase that is most widely studied for its role in regulating the p53 tumor suppressor. MDM2 antagonizes the transcriptional activity of p53 in two main ways. The N-terminal of MDM2 interacts and disables the transactivation domain of p53. In addition, the C-terminal E3 ligase region of MDM2 can attach monoubiquitin to p53 resulting in the transport of p53 from the nucleus to the cytoplasm, thereby preventing the interaction of p53 with target DNA sequences. In addition, MDM2 may also attach polyubiquitin chains to p53, resulting in the degradation of p53 by the proteosome. MDM2 may produce these effects in cooperation with the Mdmx protein. Overall, MDM2 inhibits the ability of p53 to induce cell cycle arrest or apoptosis, and may contribute to oncogenesis.
~90 kDa observed. The calculated molecular weight is 55 kDa, however MDM2 has been shown as a ~90 kDa band in western blots (Erhardt, P., et al. (1997). The Journal of Biological Chemistry. 272:15049-15052.). Uniprot describes many isoforms between 12-56 kDa, which can be highly phosphorylated and ubiquitinated.

The p53 tumor suppressor protein, a critical modulator of cellular stress responses, is activated through diverse mechanisms that result in its stabilization and transcriptional activation. p53 activity is controlled by transcriptional, translational, and post-translational regulation. The major mechanisms of p53

Cell proliferation in all rapidly renewing mammalian tissues follows a circadian rhythm that is often disrupted in advanced-stage tumors. Epidemiologic studies have revealed a clear link between disruption of circadian rhythms and cancer development in humans. Mice lacking the circadian

Stalled replication forks induce p53, which is required to maintain the replication checkpoint. In contrast to the well-established mechanisms of DNA damage-activated p53, the downstream effectors and upstream regulators of p53 during replication blockade remain to be deciphered.

MDM2, a negative regulator of p53, is elevated in many cancers that retain wild-type p53. A single nucleotide polymorphism (SNP) in the human MDM2 promoter increases the affinity of Sp1 resulting in elevated MDM2 levels. We generated mice carrying either

The p53-Mdm2 feedback loop is perceived to be critical for regulating stress-induced p53 activity and levels. However, this has never been tested in vivo. Using a genetically engineered mouse with mutated p53 response elements in the Mdm2 P2 promoter, we
