The mean pLDDT of this model is 68.4 (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 | 16% |
| 70 to 90 | Confident: backbone generally right | 45% |
| 50 to 70 | Low: treat with caution | 12% |
| Below 50 | Very low: often disordered regions | 28% |
What pLDDT means and how to read it
Single-stranded telomeric DNA-binding protein that regulates telomere replication. Has a role in both positive and negative regulation. Promotes [TG(1-3)] strand lengthening via interaction with EST1. Promotes [C(1-3)A] strand re-synthesis by DNA polymerase alpha via interaction with POL1. Negatively regulates telomere elongation of the G strand via binding with STN1 thereby inhibiting telomerase activity
Interacts with POL1, EST1, FUN12, STM1, STN1 and TEN1
Chromosome, telomere
