DESCRIPTION

Also known as NED4L_HUMAN, NEDD4L, KIAA0439, NEDL3. 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. Inhibits TGF-beta signaling by triggering SMAD2 and TGFBR1 ubiquitination and proteasome-dependent degradation. Promotes ubiquitination and internalization of various plasma membrane channels such as ENaC, SCN2A/Nav1.2, SCN3A/Nav1.3, SCN5A/Nav1.5, SCN9A/Nav1.7, SCN10A/Nav1.8, KCNA3/Kv1.3, KCNH2, EAAT1, KCNQ2/Kv7.2, KCNQ3/Kv7.3 or CLC5 (PubMed:26363003, PubMed:27445338). Promotes ubiquitination and degradation of SGK1 and TNK2. Ubiquitinates BRAT1 and this ubiquitination is enhanced in the presence of NDFIP1 (PubMed:25631046). Plays a role in dendrite formation by melanocytes (PubMed:23999003). Involved in the regulation of TOR signaling (PubMed:27694961). Ubiquitinates and regulates protein levels of NTRK1 once this one is activated by NGF (PubMed:27445338). Interacts with UBE2E3 (By similarity). Interacts with NDFIP1 and NDFIP2; this interaction activates the E3 ubiquitin-protein ligase (PubMed:26363003, PubMed:11748237). Interacts via its WW domains with SCNN1A, SCNN1B, SCNN1G, SCN1A, SCN2A, SCN3A, SCN5A, SCN8A, SCN9A, SCN10A and CLCN5 (PubMed:11696533, PubMed:14556380, PubMed:15217910, PubMed:15489223, PubMed:15548568). Interacts with SMAD2, SMAD3, SMAD6 and SMAD7 (PubMed:15496141). The phosphorylated form interacts with 14-3-3 proteins (PubMed:15677482). Interacts with TNK2 (PubMed:19144635, PubMed:20086093). Interacts with WNK1 (PubMed:20525693). Interacts with SGK1 (PubMed:11696533, PubMed:20730100). Interacts (via C2 domain) with NPC2 (PubMed:19664597). Interacts with ARRDC4 (PubMed:23236378). Interacts with KCNQ1; promotes internalization of KCNQ1 (PubMed:22024150). Interacts (via domains WW1, 3 and 4) with USP36; the interaction inhibits ubiquitination of, at least, NTRK1, KCNQ2 and KCNQ3 by NEDD4L (PubMed:27445338). Interacts with PRRG4 (via cytoplasmic domain) (PubMed:23873930).
