ID:SMUF1_HUMAN DESCRIPTION: RecName: Full=E3 ubiquitin-protein ligase SMURF1; Short=hSMURF1; EC=6.3.2.-; AltName: Full=SMAD ubiquitination regulatory factor 1; AltName: Full=SMAD-specific E3 ubiquitin-protein ligase 1; FUNCTION: E3 ubiquitin-protein ligase that acts as a negative regulator of BMP signaling pathway. Mediates ubiquitination and degradation of SMAD1 and SMAD5, 2 receptor-regulated SMADs specific for the BMP pathway. Promotes ubiquitination and subsequent proteasomal degradation of TRAF family members and RHOA. PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Interacts with TRAF4. Interacts (via HECT domain) with FBXL15 (via LRR repeats). Interacts with SMAD7 and TGFBR1; SMAD7 recruits SMURF1 to TGFBR1 and regulates TGF-beta receptor degradation. SUBCELLULAR LOCATION: Cytoplasm. Cell membrane; Peripheral membrane protein; Cytoplasmic side. DOMAIN: The C2 domain mediates membrane localization and substrate selection. PTM: Ubiquitinated by the SCF(FBXL15) complex at Lys-381 and Lys- 383, leading to its degradation by the proteasome. Lys-383 is the primary ubiquitination site. SIMILARITY: Contains 1 C2 domain. SIMILARITY: Contains 1 HECT (E6AP-type E3 ubiquitin-protein ligase) domain. SIMILARITY: Contains 2 WW domains. SEQUENCE CAUTION: Sequence=BAB13451.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
