Protein Structure
UniProt Annotation
Function Inhibits p53/TP53- and TP73/p73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Inhibits degradation of MDM2. Can reverse MDM2-targeted degradation of TP53 while maintaining suppression of TP53 transactivation and apoptotic functions. {ECO:0000269PubMed:16163388, ECO:0000269PubMed:16511572}.
Subcellular Localization Nucleus.
Disease Associations
Tissue Specificity Expressed in all tissues tested with high levels in thymus.
