The mean pLDDT of this model is 86.8 (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 | 61% |
| 70 to 90 | Confident: backbone generally right | 26% |
| 50 to 70 | Low: treat with caution | 10% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Plays a crucial role in virion assembly and budding. Forms a shell at the inner face of the plasma membrane (By similarity)
Homomultimer. Interacts with host ANP32B; this interaction promotes M nuclear localization
Virion, Host cytoplasm, Host nucleus
