The mean pLDDT of this model is 82.9 (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 | 67% |
| 70 to 90 | Confident: backbone generally right | 5% |
| 50 to 70 | Low: treat with caution | 9% |
| Below 50 | Very low: often disordered regions | 19% |
What pLDDT means and how to read it
Important for the export of protein containing nuclear export signal (NES) out of the nucleus. Stimulates the GTPase activity of GSP1 and GSP2
Interacts with GSP1 and PRP20
Cytoplasm, Nucleus
