ID:UB2D1_HUMAN DESCRIPTION: RecName: Full=Ubiquitin-conjugating enzyme E2 D1; EC=6.3.2.19; AltName: Full=Stimulator of Fe transport; Short=SFT; AltName: Full=UBC4/5 homolog; AltName: Full=UbcH5; AltName: Full=Ubiquitin carrier protein D1; AltName: Full=Ubiquitin-conjugating enzyme E2(17)KB 1; AltName: Full=Ubiquitin-conjugating enzyme E2-17 kDa 1; AltName: Full=Ubiquitin-protein ligase D1; FUNCTION: Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys- 48'-linked polyubiquitination. Mediates the selective degradation of short-lived and abnormal proteins. Functions in the E6/E6-AP- induced ubiquitination of p53/TP53. Mediates ubiquitination of PEX5 and auto-ubiquitination of STUB1, TRAF6 and TRIM63/MURF1. Ubiquitinates STUB1-associated HSP90AB1 in vitro. Lacks inherent specificity for any particular lysine residue of ubiquitin. Essential for viral activation of IRF3. Mediates polyubiquitination of CYP3A4. CATALYTIC ACTIVITY: ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine. PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: Component of a E3 ubiquitin ligase complex containing UBE2D1, SIAH1, CACYBP/SIP, SKP1, APC and TBL1X. Interacts with RNF11. INTERACTION: Q9Y3C5:RNF11; NbExp=4; IntAct=EBI-743540, EBI-396669; Q9BV68:RNF126; NbExp=3; IntAct=EBI-743540, EBI-357322; Q9Y4K3:TRAF6; NbExp=2; IntAct=EBI-743540, EBI-359276; P98170:XIAP; NbExp=2; IntAct=EBI-743540, EBI-517127; Q8ND25:ZNRF1; NbExp=4; IntAct=EBI-743540, EBI-2129250; SUBCELLULAR LOCATION: Cytoplasm. TISSUE SPECIFICITY: Ubiquitous. Up-regulated in livers of iron- overloaded patients with hereditary hemochromatosis. SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family. CAUTION: PubMed:9362508 cloned and sequenced SFT which consisted of UBE2D1 last coding exon along with intronic sequences on the 5'-end of this exon. A function in iron transport has been described.
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.
