  • 機能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. Interacts with SMAD1 and SMAD7 in order to trigger their ubiquitination and proteasome-dependent degradation. In addition, interaction with SMAD7 activates autocatalytic degradation, which is prevented by interaction with SCYE1. Forms a stable complex with the TGF-beta receptor-mediated phosphorylated SMAD2 and SMAD3. In this way, SMAD2 may recruit substrates, such as SNON, for ubiquitin-mediated degradation. Enhances the inhibitory activity of SMAD7 and reduces the transcriptional activity of SMAD2. Coexpression of SMURF2 with SMAD1 results in considerable decrease in steady-state level of SMAD1 protein and a smaller decrease of SMAD2 level.
  • 組織特異性Widely expressed.
  • パスウェイProtein modification; protein ubiquitination.
  • 配列類似性Contains 1 C2 domain.
    Contains 1 HECT (E6AP-type E3 ubiquitin-protein ligase) domain.
    Contains 3 WW domains.
  • ドメインThe second and third WW domains are responsible for interaction with the PY-motif of R-SMAD (SMAD1, SMAD2 and SMAD3).
    The C2 domain is involved in autoinhibition of the catalytic activity by interacting with the HECT domain.
  • 翻訳後修飾Auto-ubiquitinated and ubiquitinated in the presence of RNF11 and UBE2D1.
  • 細胞内局在Nucleus. Cytoplasm. Cell membrane. Membrane raft. Cytoplasmic in the presence of SMAD7. Co-localizes with CAV1, SMAD7 and TGF-beta receptor in membrane rafts.
