WB Use a concentration of 1 µg/ml. Detects a band of approximately 112 kDa (predicted molecular weight: 112 kDa).


  • 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. 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.
  • Tissue specificity
    Ubiquitously expressed, with highest levels in prostate, pancreas and kidney.
  • Pathway
    Protein modification; protein ubiquitination.
  • Sequence similarities
    Contains 1 C2 domain.
    Contains 1 HECT (E6AP-type E3 ubiquitin-protein ligase) domain.
    Contains 4 WW domains.
  • Post-translational
    Phosphorylated by SGK1 or PKA; which impairs interaction with SCNN. Interaction with YWHAH inhibits dephosphorylation.
  • Cellular localization
    Cytoplasm. May be recruited to exosomes by NDFIP1.

  • ICC/IF image of ab73386 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab73386, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
