The mean pLDDT of this model is 62.1 (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 | 10% |
| 70 to 90 | Confident: backbone generally right | 39% |
| 50 to 70 | Low: treat with caution | 14% |
| Below 50 | Very low: often disordered regions | 37% |
What pLDDT means and how to read it
Catalytic component of the SWR1 complex that mediates the ATP-dependent exchange of histone H2AZ/H2B dimers for nucleosomal H2A/H2B, leading to incorporation of histone variant H2AZ into chromatin and transcriptional regulation of selected genes by chromatin remodeling
Component of the SWR1 chromatin-remodeling complex composed of at least ACT1, ARP4, RVB1, RVB2, ARP6, YAF9, VPS71, VPS72, SWC3, SWC4, SWC5, SWC7 and SWR1, and perhaps BDF1
