The mean pLDDT of this model is 71.8 (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 | 21% |
| 70 to 90 | Confident: backbone generally right | 44% |
| 50 to 70 | Low: treat with caution | 14% |
| Below 50 | Very low: often disordered regions | 22% |
What pLDDT means and how to read it
Component of the NuA3 histone acetyltransferase complex. The NuA3 HAT complex has 2 functionally distinct forms. NuA3a binds H3K4me3, through the PHD finger of YNG1, and acetylates H3K14 at the promoter region of actively transcribed genes to promote transcription initiation. NuA3b binds H3K36me3 at the coding regions of actively transcribed genes, through the PWWP domain of PDP3, and coordinates transcription elongation
Component of the NuA3 histone acetyltransferase (HAT) complex (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:17157260). The NuA3b HAT complex contains an additional subunit, PDP3 (PubMed:25104842)
