Function

[NEDD4_RAT] 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. 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 the pathway leading to the degradation of VEGFR-2/KDFR, independently of its ubiquitin-ligase activity. Is involved in ubiquitination of ERBB4 intracellular domain E4ICD. 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).^[1] [SCNNB_RAT] Sodium permeable non-voltage-sensitive ion channel inhibited by the diuretic amiloride. Mediates the electrodiffusion of the luminal sodium (and water, which follows osmotically) through the apical membrane of epithelial cells. Controls the reabsorption of sodium in kidney, colon, lung and sweat glands. Also plays a role in taste perception.

Publication Abstract from PubMed

Nedd4 is a ubiquitin protein ligase composed of a C2 domain, three (or four) WW domains and a ubiquitin ligase Hect domain. Nedd4 was demonstrated to bind the epithelial sodium channel (alphabetagammaENaC), by association of its WW domains with PY motifs (XPPXY) present in each ENaC subunit, and to regulate the cell surface stability of the channel. The PY motif of betaENaC is deleted or mutated in Liddle syndrome, a hereditary form of hypertension caused by elevated ENaC activity. Here we report the solution structure of the third WW domain of Nedd4 complexed to the PY motif-containing region of betaENaC (TLPIPGTPPPNYDSL, referred to as betaP2). A polyproline type II helical conformation is adopted by the PPPN sequence. Unexpectedly, the C-terminal sequence YDSL forms a helical turn and both the tyrosine and the C-terminal leucine contact the WW domain. This is unlike other proline-rich peptides complexed to WW domains, which bind in an extended conformation and lack molecular interactions with residues C-terminal to the tyrosine or the structurally equivalent residue in non-PY motif WW domain targets. The Nedd4 WW domain-ENaC betaP2 peptide structure expands our understanding of the mechanisms involved in WW domain-ligand recognition and the molecular basis of Liddle syndrome.
