The mean pLDDT of this model is 88.6 (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 | 71% |
| 70 to 90 | Confident: backbone generally right | 17% |
| 50 to 70 | Low: treat with caution | 6% |
| Below 50 | Very low: often disordered regions | 5% |
What pLDDT means and how to read it
Involved in chromosome segregation during meiosis. Promotes efficient recombinational repair and functions in the protection of the genome from spontaneous and induced DNA damage like mutations and gross chromosomal rearrangements (GCRs)
Component of the SHU complex composed of at least CSM2, PSY3, SHU1 and SHU2
Cytoplasm, Nucleus
