The mean pLDDT of this model is 90.6 (very high 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 | 79% |
| 70 to 90 | Confident: backbone generally right | 15% |
| 50 to 70 | Low: treat with caution | 3% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Involved in DNA mismatch repair in slow-growing cells. Acts as a chaperone during the assembly of the 26S proteasome, specifically of the base subcomplex of the 19S regulatory complex (RC)
Interacts with RPT1, RPT2, RPT3, RPT5, RPT6, RPN1 and RPN2. Part of transient complex (BP1) containing HSM3, RPT1, RPT2 and RPT5 formed during the assembly of the 26S proteasome
