The mean pLDDT of this model is 84.9 (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 | 76% |
| 70 to 90 | Confident: backbone generally right | 5% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 15% |
What pLDDT means and how to read it
Component of the small ribosomal subunit (PubMed:36517592). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:36517592). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. During the assembly of the SSU processome in the nucleolus, many ribosome biogenesis factors, an RNA chaperone and ribosomal proteins associate with the nascent pre-rRNA and work in concert to generate RNA folding, modifications, rearrangements and cleavage as well as targeted degradation of pre-ribosomal RNA by the RNA exosome (By similarity). May play a role during erythropoiesis through regulation of…
Component of the small ribosomal subunit (PubMed:36517592). Mature ribosomes consist of a small (40S) and a large (60S) subunit (PubMed:36517592). The 40S subunit contains about 33 different proteins and 1 molecule of RNA (18S) (PubMed:36517592). The 60S subunit contains about 49 different proteins and 3 molecules of RNA (28S, 5.8S and 5S) (PubMed:36517592). Identified in a IGF2BP1-dependent…
