What is the cellular localization of MDM2?
MDM2 is predominantly localized in the nucleoplasm.
What is the tissue specificity of MDM2?
MDM2 is non-specific, expressing ubiquitously in the brain, heart, kidney, skin, and other tissues. Certain
isoforms only express in cancerous cells and not normal tissue.
With what other molecules does MDM2 interact?
Most notably, the oncogene protein MDM2 regulates transcription factor p53 by binding its transcriptional
activation domain and by E3-ubiquitin ligase activity. Ribosome proteins rpL5, rpL11, and rpL23 also bind to
MDM2, inhibiting E3 ubiquitin ligase activity and promoting the p53 pathway.
What competes with MDM2 activity?
Nutilin-3 was designed to compete with MDM2 in binding with p53, inducing activation of the p53 pathway.
What is the role of ubiquitination in MDM2 activity?
While p53 is also affected by other post-translational modifications, its stability is determined by ubiquitination
mediation of MDM2, suppressing p53 transcriptional regulation and leading to the proteosomal degradation of
How is MDM2 associated with cancer?
MDM2 inhibits the activity of the tumor-suppressive protein p53, which serves as an important factor in
promoting DNA repair or activating apoptotic pathways. Loss of p53 is associated with tumor development
What is the human ortholog of MDM2?
Human double-minute type 2 (HDM2)
In what cellular circumstances does the p53-MDM2 complex dissociate?
Cellular stress or DNA damage result in the phosphorylation and activation of p53. Phosphorylation also
prevents p53-MDM2 interaction.
Where is the gene located?
Hdm2 is located on human 12q15.
Mdm2 is located on murine 10 D2.
