The mean pLDDT of this model is 93.4 (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 | 89% |
| 70 to 90 | Confident: backbone generally right | 8% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 2% |
What pLDDT means and how to read it
Involved in ribosome biogenesis. Required for processing and efficient intra-nuclear transport of pre-60S ribosomal subunits. Interacts with the AAA-ATPase Midasin, which is essential for the ATP-dependent dissociation of a group of nonribosomal factors from the pre-60S particle
Associates with the pre-60S ribosomal particle. Interacts (via WD repeats) with uL18. Interacts (via UBL domain) with MDN1 (via VWFA/MIDAS domain). Interacts (via WD repeats) with NSA2
Nucleus, nucleolus
