The mean pLDDT of this model is 89.4 (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 | 65% |
| 70 to 90 | Confident: backbone generally right | 28% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 2% |
What pLDDT means and how to read it
Component of the transcription coactivator SAGA complex (PubMed:25216679, PubMed:28918903). SAGA acts as a general cofactor required for essentially all RNA polymerase II transcription (PubMed:25216679, PubMed:28918903). At the promoters, SAGA is required for transcription pre-initiation complex (PIC) recruitment. It influences RNA polymerase II transcriptional activity through different activities such as TBP interaction (via core/TAF module) and promoter selectivity, interaction with transcription activators (via Tra1/SPT module), and chromatin modification through histone acetylation (via HAT module) and deubiquitination (via DUB module) (PubMed:31969703). SAGA preferentially acetylates…
