Gene Name MDM2
Protein Type Enzyme
Biological Properties
General Function Involved in negative regulation of apoptosis
Specific Function E3 ubiquitin-protein ligase that mediates ubiquitination of p53/TP53, leading to its degration by the proteasome. Inhibits p53/TP53- and p73/TP73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Also acts as an ubiquitin ligase E3 toward itself and ARRB1. Permits the nuclear export of TP53/p53. Promotes proteasome-dependent ubiquitin- independent degradation of retinoblastoma RB1 protein. Inhibits DAXX-mediated apoptosis by inducing its ubiquitination and degradation
