The mean pLDDT of this model is 91.8 (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 | 84% |
| 70 to 90 | Confident: backbone generally right | 10% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 1% |
What pLDDT means and how to read it
Functions as a component of the spindle pole body (SPB) half-bridge (PubMed:10684247, PubMed:11156974, PubMed:12486115, PubMed:14504268, PubMed:8070654). At the SPB, it is recruited by KAR1 and MPS3 to the SPB half-bridge and involved in the initial steps of SPB duplication (PubMed:11156974, PubMed:12486115, PubMed:14504268, PubMed:8070654). Also involved in connection with the protein kinase KIC1 in the maintenance of cell morphology and integrity (PubMed:9813095). May play a role in vesicle-mediated transport, in a VPS13-dependent manner (PubMed:28122955)
Component of the spindle pole body (SPB), acting as the connector of microtubule arrays in the cytoplasm and the nucleoplasm, is involved in nuclear positioning before chromosome segregation, SPB separation, spindle formation, chromosome segregation, nuclear migration into the bud, nuclear reorientation after cytokinesis and nuclear fusion during conjugation. The SPB half-bridge, which is…
