The mean pLDDT of this model is 64.9 (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 | 35% |
| 70 to 90 | Confident: backbone generally right | 15% |
| 50 to 70 | Low: treat with caution | 9% |
| Below 50 | Very low: often disordered regions | 42% |
What pLDDT means and how to read it
Associates with the spindle pole body and maintains a functional interface between the nuclear membrane and the microtubule motor proteins. Involved in chromosome segregation during meiosis where it associates with the telomeres
Interacts with bqt1. The bqt1-bqt2-sad1 complex binds rap1. Also interacts with cdc31
Cytoplasm, cytoskeleton, microtubule organizing center, spindle pole body, Nucleus membrane
