A higher frequency of splice variants lacking p53 binding domain sequences was found in late-stage and high-grade ovarian and bladder carcinomas.

| + | [https://www.uniprot.org/uniprot/MDM2_HUMAN MDM2_HUMAN] E3 ubiquitin-protein ligase that mediates ubiquitination of p53/TP53, leading to its degradation 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 p53/TP53. Promotes proteasome-dependent ubiquitin-independent degradation of retinoblastoma RB1 protein. Inhibits DAXX-mediated apoptosis by inducing its ubiquitination and degradation. Component of the TRIM28/KAP1-MDM2-p53/TP53 complex involved in stabilizing p53/TP53. Also component of the TRIM28/KAP1-ERBB4-MDM2 complex which links growth factor and DNA damage response pathways. Mediates ubiquitination and subsequent proteasome degradation of DYRK2 in nucleus. Ubiquitinates IGF1R and promotes it to proteasomal degradation.<ref>PMID:12821780</ref> <ref>PMID:15053880</ref> <ref>PMID:15195100</ref> <ref>PMID:16337594</ref> <ref>PMID:15632057</ref> <ref>PMID:17290220</ref> <ref>PMID:19098711</ref> <ref>PMID:19219073</ref> <ref>PMID:19965871</ref> <ref>PMID:20858735</ref> <ref>PMID:20173098</ref> | ||
