The mean pLDDT of this model is 62.9 (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 | 9% |
| 70 to 90 | Confident: backbone generally right | 42% |
| 50 to 70 | Low: treat with caution | 18% |
| Below 50 | Very low: often disordered regions | 32% |
What pLDDT means and how to read it
Involved in transcriptional activation. Component of the SWI/SNF complex, an ATP-dependent chromatin-remodeling complex, which is required for the positive and negative regulation of gene expression of a large number of genes. It changes chromatin structure by altering DNA-histone contacts within a nucleosome, leading eventually to a change in nucleosome position, thus facilitating or repressing binding of gene-specific transcription factors
Component of the SWI/SNF global transcription activator complex. The 1.14 MDa SWI/SNF complex is composed of 11 different subunits: one copy each of SWI1, SNF2/SWI2, SNF5, SNF12/SWP73, ARP7/SWP61, ARP9/SWP59; two copies each of SWI3, SNF6, SNF11, SWP82; and three copies of TAF14/SWP29
