The mean pLDDT of this model is 87.5 (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 | 73% |
| 70 to 90 | Confident: backbone generally right | 11% |
| 50 to 70 | Low: treat with caution | 11% |
| Below 50 | Very low: often disordered regions | 5% |
What pLDDT means and how to read it
Involved in the biogenesis of the 60S ribosomal subunit
Component of the pre-66S ribosomal particle. Interacts with NOP7, RRP1 and RRP5
