  • a HECT domain (homologous to the E6-AP carboxyl terminus) and ubiquitin-binding site located in the HECT domain that plays a role in the regulation of polyubiquitin chain length
  • a C2 domain that binds phosphoinositides particularly PI(3)P, which is enriched on endosomal membranes (Klos Dehring 2008)and has a Ca2+-dependent association with cellular membranes
  • four WW domains
    interspecies homolog to yeast S.cerevisiae Rsp5
    homolog to murine Nedd 4.2
  • NEDD4 gene family
  • CATEGORY regulatory
    SUBCELLULAR LOCALIZATION     plasma membrane
    text C2 domain is necessary for translocating NEDD4L to the plasma membrane to effectively interact with cell surface SCNN1A, SCNN1B, SCNN1C
    basic FUNCTION
  • playing a role in the regulation of ENaC function (negative regulation of epithelial sodium channel)
  • ubiquitin-protein ligase (ubiquitination)
  • major inactivating enzyme for SCNN1A in urinary tubular cells
  • in response to Ca2+, may be mobilized to the apical membrane via its C2 domain, where it binds SCNN1A via NEDD4L-WW:SCNN1A-PY motif interactions, leading to ubiquitination of the channel by the NEDD4L-HECT domain, with subsequent channel endocytosis and lysosomal degradation
  • regulator of renal sodium channels, that is shown to play a broader role as a general modulator of Smad turnover during TGF-beta signal transduction
  • regulate the epithelial Na+ channel by its ubiquitination and removal from the plasma membrane
  • may regulate TRPV6 protein abundance in intestinal epithelia by controlling TRPV6 ubiquitination (
  • may regulate TRPV6 ubiquitination and degradation at different rates by regulating their interaction (
  • can suppress the onset of cystic fibrosis symptoms by inhibiting SCNN1A in lung epithelia
  • having protective regulatory role against the development of cystic fibrosis
  • ubiquitin ligase that targets the epithelial sodium channel for degradation, and plays a role in the progression of various cancers
  • regulates the amiloride-sensitive epithelial Na+ channel (ENaC/SCNN1) to mediate Na+ homeostasis
    a component
  • member of HECT class of E3 ubiquitin ligases
  • CAV3, NEDD4L, and KCNH2 likely form a complex in the plasma membrane
    small molecule
  • ubiquination of RFA1
  • potent negative regulator of amiloride-sensitive epithelium sodium channel SCNN1A, SCNN1B, SCNN1G, SCNN1D
  • phosphorylated form of NEDD4L interacts with 14-3-3 proteins (interaction is dependent on SGK1-catalyzed phosphorylation at Ser-468)
  • differentially interacts with and regulates TTYH1-3, will be important for understanding mechanisms controlling Tweety proteins in physiology and disease
  • NEDD4L binds TNK2 via a conserved PPXY-containing region
  • binds the PY motif of SCNN1A C-terminals and catalyzes ubiquitination of the NH2 terminal of the protein for subsequent degradation
  • phosphorylation of the Pro-Gly-Ser-Pro motif within L1 of SCN8A is necessary for stress-induced current modulation, with positive or negative regulation depending upon the availability of the C-terminal Pro-Ser-Tyr motif to bind NEDD4L
  • NEDD4L mediated ubiquitination regulates the cell surface expression of SLC5A7
  • NEDD4, NEDD4L and ITCH mediate poly-ubiquitination of AMOT/p130
  • NDRG1 upregulates neural precursor cell expressed developmentally downregulated 4-like (NEDD4L) and GLI-similar-3 (GLIS3)
  • CNKSR3 physically interacts with SCNN1A, B, D, NEDD4L, and SGK1 and stimulates SCNN1A, SCNN1B, SCNN1D function in a PDZ domain-dependent, aldosterone-induced manner
  • CAV3 enhances ubiquitin ligase NEDD4L interaction with mature KCNH2 channels in the plasma membrane, leading to decreased channel expression
  • RAB4A decreases the KCNH2 density at the plasma membrane by increasing the endogenous NEDD4L expression
  • WNK3 is an activator of SLC12A3, and NEDD4L is an inhibitor
  • proline-rich exons are modular cassettes that convert WNK1 into a NEDD4L substrate, thereby linking aldosterone and other NEDD4L-suppressing antinatriuretic hormones to SLC12A3 phosphorylation status
  • NDFIP1 is primarily localized in the Golgi apparatus where it recruits NEDD4L to mediate the degradation of mature KCNH2 proteins during channel trafficking to the plasma membrane
  • USP36 binds to and regulates the actions of NEDD4L over different substrates affecting their expression and functions
  • important negative regulatory function for NEDD4L and NDFIP1 in IgE-dependent mast cell activity
  • cell & other
    inhibited by phosphorylation via a serum- and glucocorticoid-inducible protein kinase (SGK1), which serves as a mechanism to inhibit the ubiquitination-dependent degradation of SCNN1G

  • to essential hypertension
  • to beta-blocker or diuretic-induced blood pressure reduction and prevention of cardiovascular disease
  • Variant & Polymorphism SNP

  • Therapy target
    implications of SCNN1A/NEDD4L systems might reach fruition in the discovery of molecular targets that could serve as therapeutic point of actions for the pharmaceutical management of essential hypertension in the future
    respiratoryCF (mucoviscidosis) 
    search for compounds that enhance NEDD4L activity could provide a useful approach to develop unique treatments for cystic fibrosis
    drugs which inhibit the interaction between SLC5A7 and NEDD4L might be useful for diseases involving decrease in acetylcholine level such as Alzheimer disease
  • specific ablation of Nedd4L in lung epithelia in mice leads to the development of cystic fibrosis-like symptoms, most likely caused by increased SCNN1A function
