The mean pLDDT of this model is 70.6 (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 | 42% |
| 50 to 70 | Low: treat with caution | 14% |
| Below 50 | Very low: often disordered regions | 23% |
What pLDDT means and how to read it
Part of a complex involved in cell-cycle-dependent transcription. SWI4 and SWI6 are required for formation of the cell-cycle box factor-DNA complex. The repeated element in the upstream region of HO (5'-CACGAAAA-3') is called the cell cycle box (CCB)
Component of the transcription complex MCB-binding factor (MBF) composed of SWI6 and MBP1. Component of the transcription complex SCB-binding factor (SBF) composed of SWI6 and SWI4. Interacts with MSA1 and STB1
