The mean pLDDT of this model is 78.8 (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 | 45% |
| 70 to 90 | Confident: backbone generally right | 24% |
| 50 to 70 | Low: treat with caution | 22% |
| Below 50 | Very low: often disordered regions | 10% |
What pLDDT means and how to read it
Chemotactic activity for lymphocytes but not for monocytes or neutrophils. In thymus, mediates medullary accumulation of thymic dendritic cells and contributes to regulatoy T cell development, playing a role in self-tolerance establishment
