The mean pLDDT of this model is 57.7 (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 | 3% |
| 70 to 90 | Confident: backbone generally right | 31% |
| 50 to 70 | Low: treat with caution | 27% |
| Below 50 | Very low: often disordered regions | 39% |
What pLDDT means and how to read it
Catalytic component of the RPD3C(S) histone deacetylase complex responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression, DNA damage response, osmotic stress response and developmental events
Component of the RPD3C(S) complex composed of at least EAF3, RCO1, RPD3, SIN3, and UME1
