The mean pLDDT of this model is 72.0 (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 | 1% |
| 70 to 90 | Confident: backbone generally right | 62% |
| 50 to 70 | Low: treat with caution | 24% |
| Below 50 | Very low: often disordered regions | 13% |
What pLDDT means and how to read it
Involved in microtubule organization by the microtubule organizing center, the spindle pole body (SPB). Probably part of the microtubule attachment site at the SPB
Interacts with TUB4, SPC72 and SPC97
Nucleus, Cytoplasm, cytoskeleton, microtubule organizing center, spindle pole body
