Interacts with p53/TP53, TP73/p73, RBL5 and RP11. Binds specifically to RNA. Can interact with RB1, E1A-associated protein EP300 and the E2F1 transcription factor. Forms a ternary complex with p53/TP53 and WWOX. Interacts with CDKN2AIP, RFWD3, USP7, PYHIN1, and RBBP6. Interacts with ARRB1 and ARRB2. Interacts with PSMA3. Found in a trimeric complex with MDM2, MDM4 and USP2. Interacts with USP2 (via N-terminus and C-terminus). Interacts with MDM4. Part of a complex with MDM2, DAXX, RASSF1 and USP7. Part of a complex with DAXX, MDM2 and USP7. Interacts directly with DAXX and USP7. Interacts (via C-terminus) with RASSF1 isoform A (via N-terminus); the interaction is independent of TP53. Interacts with APEX1; leading to its ubiquitination and degradation. Interacts with RYBP; this inhibits ubiquitination of TP53. Identified in a complex with RYBP and p53/TP53. Also a component of the TRIM28/KAP1-MDM2-p53/TP53 complex involved in regulating p53/TP53 stabilization and activity. Binds directly both p53/TP53 and TRIM28. Component of the TRIM28/KAP1-ERBB4-MDM2 complex involved in connecting growth factor responses with DNA damage. Interacts directly with both TRIM28 and ERBB4 in the complex. Interacts with DYRK2. Interacts with IGF1R. Interacts with TRIM13; the interaction ubiquitinates MDM2 leading to its proteasomal degradation. Interacts with SNAI1; this interaction promotes SNAI1 ubiquitination. Interacts with NOTCH1 (via intracellular domain). Interacts with FHIT. Interacts with RFFL and RNF34; the interaction stabilizes MDM2. Interacts with CDK5RAP3 and CDKN2A/ARF; form a ternary complex involved in regulation of p53/TP53 (PubMed:16173922). Interacts with MTA1. Interacts with AARB2. Interacts with MTBP. Interacts with PML. Interacts with TBRG1. Interacts with the 5S RNP which is composed of the 5S RNA, RPL5 and RPL11; the interaction is direct, occurs in the nucleoplasm and negatively regulates MDM2-mediated TP53 ubiquitination and degradation (PubMed:15195100, 24120868). Interacts with ADGRB1; the interaction results in inhibition of MDM2-mediated ubiquitination and degradation of DLG4/PSD95, promoting DLG4 stability and regulating synaptic plasticity (By similarity). Interacts with RPL23A; this interaction may promote p53/TP53 polyubiquitination (PubMed:26203195). Interacts with NDUFS1 (PubMed:30879903). (Microbial infection) Interacts with herpes virus 8 protein v-IRF4. (Microbial infection) Interacts with and ubiquitinates HIV-1 Tat.
