The mean pLDDT of this model is 78.8 (confident overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.
| pLDDT band | Meaning | Share of residues |
|---|---|---|
| Above 90 | Very high: backbone and side chains are usually accurate | 14% |
| 70 to 90 | Confident: backbone generally right | 65% |
| 50 to 70 | Low: treat with caution | 12% |
| Below 50 | Very low: often disordered regions | 9% |
What pLDDT means and how to read it
Component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through the cell cycle (PubMed:11739784, PubMed:18485873, PubMed:27120157, PubMed:27509861). Together with the RING-H2 protein ANAPC11, forms the catalytic component of the E3 ubiquitin ligase complex (PubMed:11739784, PubMed:18485873, PubMed:27120157, PubMed:27509861). APC/C acts by mediating ubiquitination and subsequent degradation of target proteins: it mainly mediates the formation of 'Lys-11'-linked polyubiquitin chains and, to a lower extent, the formation of 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains (PubMed:11739784, PubMed:18485873). APC/C…
Component of the anaphase promoting complex/cyclosome (APC/C), composed of ANAPC1, ANAPC2, CDC27/ANAPC3, ANAPC4, ANAPC5, CDC16/ANAPC6, ANAPC7, CDC23/ANAPC8, ANAPC10, ANAPC11, CDC26/ANAPC12, ANAPC13, ANAPC15 and ANAPC16 (PubMed:25043029, PubMed:26083744, PubMed:27120157, PubMed:27509861). APC/C associates with CDC20 to form the CDC20-APC/C complex, which is crucial for metaphase/anaphase…
