Protein Information (annotations from UniProt)

Database IDHIV0008517
UniProt IDQ96PU5
Primary gene name(s)NEDD4L
Synonym gene name(s)KIAA0439, NEDL3
Protein nameE3 ubiquitin-protein ligase NEDD4-like
Protein functionE3 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, Nav1.2, Nav1.3, Nav1.5, Nav1.7, Nav1.8, Kv1.3, EAAT1 or CLC5. 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. {ECO:0000250|UniProtKB:Q8CFI0, ECO:0000269|PubMed:12911626, ECO:0000269|PubMed:15040001, ECO:0000269|PubMed:15217910, ECO:0000269|PubMed:15489223, ECO:0000269|PubMed:15496141, ECO:0000269|PubMed:15576372, ECO:0000269|PubMed:19144635, ECO:0000269|PubMed:23999003, ECO:0000269|PubMed:25631046}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:15496141, ECO:0000269|PubMed:18819914}. Note=May be recruited to exosomes by NDFIP1.
