The mean pLDDT of this model is 79.3 (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 | 64% |
| 70 to 90 | Confident: backbone generally right | 10% |
| 50 to 70 | Low: treat with caution | 3% |
| Below 50 | Very low: often disordered regions | 23% |
What pLDDT means and how to read it
Required for the assembly and/or stability of the 40S ribosomal subunit (PubMed:23873042, PubMed:25601755). Required for the processing of the 20S rRNA-precursor to mature 18S rRNA in a late step of the maturation of 40S ribosomal subunits (PubMed:23873042, PubMed:25601755). Also functions as a cell surface receptor for laminin (By similarity). Plays a role in cell adhesion to the basement membrane and in the consequent activation of signaling transduction pathways (By similarity). May play a role in cell fate determination and tissue morphogenesis (By similarity). Also acts as a receptor for several other ligands, including the pathogenic prion protein, viruses, and bacteria. Acts as a…
Monomer (37LRP) and homodimer (67LR) (By similarity). Component of the small ribosomal subunit (PubMed:23873042, PubMed:25601755, PubMed:29856316, PubMed:31609474, PubMed:32286223, PubMed:33296660, PubMed:35679869, PubMed:35709277, PubMed:35822879, PubMed:36653451). Mature ribosomes consist of a small (40S) and a large (60S) subunit (PubMed:23873042, PubMed:25601755, PubMed:29856316,…
