ID:UBC12_HUMAN DESCRIPTION: RecName: Full=NEDD8-conjugating enzyme Ubc12; EC=6.3.2.-; AltName: Full=NEDD8 carrier protein; AltName: Full=NEDD8 protein ligase; AltName: Full=Ubiquitin-conjugating enzyme E2 M; FUNCTION: Accepts the ubiquitin-like protein NEDD8 from the UBA3- NAE1 E1 complex and catalyzes its covalent attachment to other proteins. The specific interaction with the E3 ubiquitin ligase RBX1, but not RBX2, suggests that the RBX1-UBE2M complex neddylates specific target proteins, such as CUL1, CUL2, CUL3 and CUL4. Involved in cell proliferation. CATALYTIC ACTIVITY: ATP + NEDD8 + protein lysine = AMP + diphosphate + protein N-NEDD8yllysine. PATHWAY: Protein modification; protein neddylation. SUBUNIT: Interacts with UBA3, DCUN1D1 and RBX1. INTERACTION: Q8TBC4:UBA3; NbExp=2; IntAct=EBI-1041660, EBI-717567; DOMAIN: Both the N-terminal docking peptide and the catalytic core domain must bind the UBA3-NAE1 complex simultaneously for optimal transfer of NEDD8. PTM: The acetylation of Met-1 is cotranslational, and not regulatory. The N-acetylmethionine increases affinity for DCUN1D1 by about 2 orders of magnitude and is crucial for NEDD8 transfer to cullins. SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family. UBC12 subfamily.
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.
