The mean pLDDT of this model is 77.4 (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 | 6% |
| 70 to 90 | Confident: backbone generally right | 75% |
| 50 to 70 | Low: treat with caution | 17% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Acts as a regulatory subunit of the 26S proteasome which is involved in the ATP-dependent degradation of ubiquitinated proteins
