The mean pLDDT of this model is 76.8 (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 | 59% |
| 70 to 90 | Confident: backbone generally right | 5% |
| 50 to 70 | Low: treat with caution | 13% |
| Below 50 | Very low: often disordered regions | 23% |
What pLDDT means and how to read it
Regulator of mitochondrial ribosome biogenesis and translation. Binds to mitochondrial ribosomal RNAs 16S, 12S and 7S and targets NSUN4 RNA methyltransferase to the mitochondrial large ribosomal subunit (39S)
Heterodimer with NSUN4; this interaction may be required for NSUN4 recruitment to the mitochondrial large ribosomal subunit
