The mean pLDDT of this model is 75.1 (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 | 37% |
| 70 to 90 | Confident: backbone generally right | 30% |
| 50 to 70 | Low: treat with caution | 12% |
| Below 50 | Very low: often disordered regions | 21% |
What pLDDT means and how to read it
Histone-binding component of the NuA3a histone acetyltransferase complex. Targets the NuA3a HAT complex via histone H3K4me3 to facilitate transcription initiation at promoter regions. SAS3 then acetylates H3K14, leading to transcription initiation at a subset of genes. YNG1 is required for the HAT activity of NuA3 but not for its integrity. Mediates the interaction of SAS3 with nucleosomes
Component of the NuA3 histone acetyltransferase (HAT) complex (PubMed:12077334, PubMed:17157260). The NuA3 HAT complex has 2 functionally distinct forms that participate in transcription (PubMed:25104842). The NuA3a HAT complex is composed of at least NTO1, SAS3, TAF14, YNG1 and EAF6 (PubMed:12077334, PubMed:17157260). The NuA3b HAT complex contains an additional subunit, PDP3 (PubMed:25104842).…
