The mean pLDDT of this model is 90.1 (very high 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 | 80% |
| 70 to 90 | Confident: backbone generally right | 9% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 6% |
What pLDDT means and how to read it
Autophagy factor required for autophagosome formation. Stabilizes ATG13, protecting it from proteasomal degradation
Interacts with ATG13 (PubMed:19287211, PubMed:19597335, PubMed:26299944). Associates with a complex composed of ATG13, ULK1 and RB1CC1; the association with this complex requires the presence of ATG13 (PubMed:19287211, PubMed:19597335)
