ID:UBE3C_HUMAN DESCRIPTION: RecName: Full=Ubiquitin-protein ligase E3C; EC=6.3.2.-; AltName: Full=HectH2; FUNCTION: E3 ubiquitin-protein ligase that accepts ubiquitin from the E2 ubiquitin-conjugating enzyme UBE2D1 in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Can assemble unanchored poly-ubiquitin chains in either 'Lys-29'- or 'Lys-48'-linked polyubiquitin chains. Has preference for 'Lys-48' linkages. It can target itself for ubiquitination in vitro and may promote its own degradation in vivo. PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Interacts with 26S proteasomes. Interacts (via the N- terminal) with CAND2; the interaction stimulates ubiquitination of CAND2 in vitro. May interact (via the HECT domain) with UBE2D1 and, less efficiently, with UBE2L3. SUBCELLULAR LOCATION: Nucleus (Potential). TISSUE SPECIFICITY: Highly expressed in skeletal muscle. Detected at much lower levels in kidney and pancreas. DOMAIN: The C-terminal is necessary and sufficient for the poly- ubiquitin chain assembly. MISCELLANEOUS: A cysteine residue is required for ubiquitin- thioester formation. SIMILARITY: Contains 1 HECT (E6AP-type E3 ubiquitin-protein ligase) domain. SIMILARITY: Contains 1 IQ domain. SEQUENCE CAUTION: Sequence=BAA02799.2; Type=Erroneous initiation; Note=Translation N-terminally shortened;
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.
