The mean pLDDT of this model is 76.4 (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 | 44% |
| 70 to 90 | Confident: backbone generally right | 29% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 22% |
What pLDDT means and how to read it
Component of the nuclear pore complex, a complex required for the trafficking across the nuclear membrane
Component of the p62 complex, a complex composed of NUP62, NUP54, and the isoform p58 and isoform p45 of NUP58. Interacts with NUTF2
Nucleus, nuclear pore complex, Nucleus membrane
