The mean pLDDT of this model is 80.1 (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 | 22% |
| 70 to 90 | Confident: backbone generally right | 56% |
| 50 to 70 | Low: treat with caution | 19% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Acts as a component of the essential kinetochore-associated NDC80 complex, which is involved in chromosome segregation and spindle checkpoint activity
Component of the NDC80 complex, which consists of TID3/NDC80, NUF2, SPC24 and SPC25. The NDC80 complex is formed by two subcomplexes, TID3/NDC80-NUF2 and SPC24-SPC25, which are joined end-to-end through their coiled-coil domains. It has a rod-like structure with a length of 570 Angstroms and globular domains at either end. The TID3/NDC80-NUF2 globular domains are probably directed to…
