The mean pLDDT of this model is 77.0 (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 | 43% |
| 70 to 90 | Confident: backbone generally right | 26% |
| 50 to 70 | Low: treat with caution | 15% |
| Below 50 | Very low: often disordered regions | 16% |
What pLDDT means and how to read it
Negative regulator of flowering controlling the H4K5 acetylation levels in the FLC and FT chromatin. Positively regulates FLC expression. Component of the transcription factor IID (TFIID) complex that is essential for mediating regulation of RNA polymerase transcription. Component of the SWR1 complex which mediates the ATP-dependent exchange of histone H2A for the H2A variant HZT1 leading to transcriptional regulation of selected genes by chromatin remodeling. Component of a NuA4 histone acetyltransferase complex which is involved in transcriptional activation of selected genes principally by acetylation of nucleosomal histones H4 and H2A
Component of the TFIID complex. TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs) whose MWs range from 14-217 kDa. Interacts with TAF1, TAF4B and TAF12B. Component of the SWR1 chromatin-remodeling complex. Interacts with FLX, a component of the transcription activator complex FRI-C (PubMed:17340043, PubMed:21282526). Interacts with SWC4, and with EAF1A…
