Function
E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Specifically ubiquitinates 'Lys-63' in target proteins (By similarity). Monoubiquitinates IGF1R at multiple sites, thus leading to receptor internalization and degradation in lysosomes. Ubiquitinates FGFR1, leading to receptor internalization and degradation in lysosomes. Involved in ubiquitination of ERBB4 intracellular domain E4ICD1 (PubMed:19193720). Predominantly involved in ubiquitination of membrane bound forms of ERBB4 rather than processed precursors and intermediate membrane-anchored 80 kDa fragments (m80HER4), with a lesser role in ubiquitination of ERBB4 intracellular domain E4ICD1 (PubMed:19047365). Promotes ubiquitination of RAPGEF2. Involved in the pathway leading to the degradation of VEGFR-2/KDFR, independently of its ubiquitin-ligase activity. Part of a signaling complex composed of NEDD4, RAP2A and TNIK which regulates neuronal dendrite extension and arborization during development. Ubiquitinates TNK2 and regulates EGF-induced degradation of EGFR and TNF2 (By similarity). Involved in the ubiquitination of ebola virus VP40 protein and this ubiquitination plays a role in facilitating viral budding. Ubiquitinates BRAT1 and this ubiquitination is enhanced in the presence of NDFIP1. UniProt

Subunit Structure
Binds SCNN1A, SCNN1B and SCNN1G. Interacts with NDFIP1 and NDFIP2; this interaction activates the E3 ubiquitin-protein ligase and may induce its recruitment to exosomes. Interacts with UBE2D2 (PubMed:9182527). Binds, in vitro, through the WW2 and WW3 domains, to neural isoforms of ENAH that contain the PPSY motif (PubMed:9407065). Interacts with BEAN1, LITAF, RNF11, WBP1, WBP2, PMEPAI and PRRG2 (PubMed:11042109). Interacts with murine leukemia virus Gag polyprotein (via PPXY motif) (PubMed:15908698). Interacts (via C2 domain) with GRB10 (via SH2 domain) (PubMed:12697834, PubMed:15060076, PubMed:18286479, PubMed:20980250). Interacts with ERBB4 (PubMed:19193720, PubMed:19047365). Interacts with TNIK; the interaction is direct, allows the TNIK-dependent recruitment of RAP2A and its ubiquitination by NEDD4 (PubMed:20159449). Interacts (via WW3 domain) with TNK2; EGF promotes this interaction. Interacts (via WW3 domain) with FGFR1 (via C-terminus). Interacts with OTUD7B (By similarity). Interacts with ISG15 (By similarity). Interacts (via WW domain) with RAPGEF2; this interaction leads to ubiquitination and degradation via the proteasome pathway. Interacts (via WW domains) with ARRDC3 (via PPXY motifs) (By similarity). Interacts with LAPTM4B; may play a role in the lysosomal sorting of LAPTM4B (By similarity). Interacts with ZBTB7B (PubMed:28784777). UniProt
Domain
The WW domains mediate interaction with PPxY motif-containing proteins (By similarity). The WW domains mediate interaction with LITAF, RNF11, WBP1, WBP2, PMEPAI, NDFIP1 and PRRG2 (PubMed:11042109). UniProt

Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
