Application Abreviews Notes
WB 1/1000 - 1/5000. Detects a band of approximately 110-135 kDa (predicted molecular weight: 112 kDa).
IP 1/10 - 1/100.
  • Application notes
    Is unsuitable for ICC/IF or IHC-P.
  • Target

    • 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.
