The mean pLDDT of this model is 79.6 (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 | 55% |
| 70 to 90 | Confident: backbone generally right | 20% |
| 50 to 70 | Low: treat with caution | 11% |
| Below 50 | Very low: often disordered regions | 15% |
What pLDDT means and how to read it
Involved in the intranuclear transport of ribosomal precursors
Interacts with MAK21/NOC1 and NOC3. Forms a nucleolar complex with MAK21 that binds to 90S and 66S pre-ribosomes, as well as a nuclear complex with NOC3 that binds to 66S pre-ribosomes
Nucleus, nucleolus
