The mean pLDDT of this model is 83.9 (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 | 47% |
| 70 to 90 | Confident: backbone generally right | 37% |
| 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. May play a part in the quality control of pre-60S particles. Under normal, rapid growth conditions, high levels of NSA2 would allow the progression of pre-60S particles through the ITS2 processing
Component of the pre-66S ribosomal particle. Interacts with NOP7 and RRP1. Interacts with RSA4 (via WD repeats) (PubMed:25404745)
