Monomer. Interacts (via WW domains) with OCNL (By similarity). Interacts (via WW domains) with NOTCH1 (By similarity). Interacts (via WW domains) with JUN (By similarity). Interacts with JUNB; the interaction promotes ITCH-mediated ubiquitination and degradation of JUNB (PubMed:16387660). Interacts with FYN; the interaction phosphorylates ITCH on Tyr-420 decreasing binding of JUNB (PubMed:16387660). Interacts (via WW domain 2) with N4BP1; the interaction inhibits the E3 ubiquitin-protein ligase activity (By similarity). Interacts with NDFIP1 and NDFIP2; this interaction activates the E3 ubiquitin-protein ligase and may induce its recruitment to exosomes (By similarity). Interacts with ARHGEF7 (PubMed:17652093). Interacts with RNF11 (PubMed:14559117, PubMed:19131965). Interacts (via the WW 1 domain) with NFE2 (via the PXY motif 1); the interaction promotes 'Lys-63'-linked ubiquitination of NFE2, retains it in the cytoplasm and prevents its transactivation activity (PubMed:11318614, PubMed:18718448). Interacts (via WW domains) with CXCR4 (via C-terminus); the interaction depends on CXCR4 phosphorylation (PubMed:19116316). Found in a complex with E3 ligase DTX3L and ESCRT-0 components HGS and STAM (PubMed:24790097). Interacts with DTX3L (via C-terminus); the interaction is increased upon CXCL12 stimulation and inhibits ITCH catalytic activity (the interaction is direct) (PubMed:24790097). Interacts with HGS (PubMed:14602072). Interacts (via WW domains) with PCBP2 within a complex containing ITCH, MAVS and PCBP2 (PubMed:19881509). Interacts (via WW domains) with TXNIP (via C-terminus) (PubMed:20068034). Interacts with p15 BID (PubMed:20392206). Interacts with ERBB4 (PubMed:20858735). Interacts with DTX1 (PubMed:17028573). Interacts with SPART (PubMed:19580544). Interacts with SNX9 and SNX18 (PubMed:20491914). Interacts (via its WW domains) with ATN1 (PubMed:9647693). Interacts (via WW domains) with SGK3 (PubMed:16888620). Interacts with CBLC (PubMed:12226085). Interacts with OTUD7B (PubMed:22179831). Interacts (via WW domain 1,2 and 3) with PI4K2A; the interaction inhibits PI4K2A catalytic activity and promotes ITCH catalytic activity (PubMed:23146885). Interacts with ARRDC4 (PubMed:23236378). Part of a complex containing ITCH, NDFIP1 and MAP3K7 (By similarity). Interacts with UBE2L3; the interaction is mediated by NDFIP1 (PubMed:25632008). Interacts with MAPK8/JNK1 (By similarity). Interacts (via WW domains) with ARRDC1 (via PPxY motifs); the interaction is direct and participates in the recruitment of the ubiquitin-protein ligase ITCH to the NOTCH1 receptor (PubMed:21191027, PubMed:23886940). Interacts (via WW domains) with ARRDC2 (PubMed:21191027). Interacts (via WW domains) with ARRDC3 (PubMed:21191027, PubMed:23886940). Interacts directly with LDLRAD3; this interaction promotes ITCH auto-ubiquitination leading to its degradation (PubMed:26854353). (Microbial infection) Interacts with Epstein-Barr virus LMP2A. (Microbial infection) Interacts with Human cytomegalovirus (HCMV) protein UL42; this interaction induces ubiquitination and degradation of ITCH. (Microbial infection) Interacts with herpesvirus 1 (HHV-1) UL56 protein; this interaction induces ubiquitination and probably degradation of ITCH. (Microbial infection) Interacts with herpesvirus 2 (HHV-2) UL56 protein. (Microbial infection) Interacts with varicella-zoster virus (VZV) Orf0 protein. (Microbial infection) Interacts with herpesvirus 6A (HHV-6A) U24 protein. (Microbial infection) Interacts with ebola virus protein VP40; this interaction is required for efficient viral egress from the infected cell. (Microbial infection) Interacts with influenza A virus matrix protein 1.
