The mean pLDDT of this model is 52.8 (low 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 | 14% |
| 70 to 90 | Confident: backbone generally right | 9% |
| 50 to 70 | Low: treat with caution | 8% |
| Below 50 | Very low: often disordered regions | 69% |
What pLDDT means and how to read it
Stimulates mRNA translation
Interacts with PABPC1 (PubMed:20573744, Ref.23). Interacts with RACK1 (PubMed:20573744). Associates with polysomes via the 40S ribosomal subunit (PubMed:20573744)
