Target intelligence / Profile preview

MDM2 Proto-Oncogene (None)

Target
None
Molecular classification
E3 Ubiquitin Ligase, Transcription factor regulator
01

Overview

The MDM2 proto-oncogene encodes an E3 ubiquitin-protein ligase that primarily regulates the p53 tumor suppressor protein by targeting it for proteasomal degradation. It inhibits p53’s transcriptional activity, promoting cell survival and proliferation. Overexpression or amplification of MDM2 is frequently observed in various cancers, making it a significant target for anti-cancer drug development.
