Rabbit Anti-SMURF2, NT (E3 Ubiquitin-protein Ligase SMURF2, Smad Ubiquitination Regulatory Factor 2, Ubiquitin-protein Ligase SMURF2, Smad-specific E3 Ubiquitin Ligase 2, hSMURF2)
SMURF2, a 748aa ubiquitin E3 ligase that is 83% identical to SMURF1, codes for a C2-WW-HECT domain ubiquitin ligase that associates constitutively with SMAD7. Binding to SMAD7 induces export of SMURF2 and recruitment to the activated transforming growth factor-beta receptor (TGFBR), where it causes receptor and SMAD7 degradation. A strong interaction of second and third SMURF2 WW domains has been identified with SMAD1, SMAD2, and SMAD3, but not SMAD4. Western blot analysis showed that SMURF2 selectively downregulates the transcription of SMAD2 and SMAD1, but not SMAD3. The nuclear SMURF2/phosphorylated SMAD2 interaction is requires TGFB1.
