ID:UB2E3_HUMAN DESCRIPTION: RecName: Full=Ubiquitin-conjugating enzyme E2 E3; EC=6.3.2.19; AltName: Full=UbcH9; AltName: Full=Ubiquitin carrier protein E3; AltName: Full=Ubiquitin-conjugating enzyme E2-23 kDa; AltName: Full=Ubiquitin-protein ligase E3; FUNCTION: Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys- 11'- and 'Lys-48'-, as well as 'Lys-63'-linked polyubiquitination. Participates in the regulation of transepithelial sodium transport in renal cells. May be involved in cell growth arrest. CATALYTIC ACTIVITY: ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine. PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: The ubiquitin-loaded form interacts specifically with importin-11 (IPO11), leading to its import into the nucleus (By similarity). Interacts with NEDD4L. SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Shuttles between the nucleus and cytoplasm in a IPO11-dependent manner. TISSUE SPECIFICITY: Ubiquitously expressed at low levels. Highly expressed in skeletal muscle. SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
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.
