The mean pLDDT of this model is 80.6 (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 | 52% |
| 70 to 90 | Confident: backbone generally right | 26% |
| 50 to 70 | Low: treat with caution | 4% |
| Below 50 | Very low: often disordered regions | 19% |
What pLDDT means and how to read it
Component of the NOP7 complex, which is required for maturation of the 25S and 5.8S ribosomal RNAs and formation of the 60S ribosome
Component of the NOP7 complex, composed of ERB1, NOP7 and YTM1. The complex is held together by ERB1, which interacts with NOP7 via its N-terminal domain and with YTM1 via a high-affinity interaction between the seven-bladed beta-propeller domains of the 2 proteins. The NOP7 complex associates with the 66S pre-ribosome. Also interacts with NOG1
