The mean pLDDT of this model is 65.7 (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 | 12% |
| 70 to 90 | Confident: backbone generally right | 44% |
| 50 to 70 | Low: treat with caution | 17% |
| Below 50 | Very low: often disordered regions | 28% |
What pLDDT means and how to read it
Mitotic kinesin required for chromosome passenger complex (CPC)-mediated cytokinesis. Following phosphorylation by PLK1, involved in recruitment of PLK1 to the central spindle (By similarity). Interacts with guanosine triphosphate (GTP)-bound forms of RAB6A and RAB6B. May act as a motor required for the retrograde RAB6 regulated transport of Golgi membranes and associated vesicles along microtubules. Has a microtubule plus end-directed motility
Golgi apparatus, Cytoplasm, cytoskeleton, spindle
