The mean pLDDT of this model is 91.1 (very high 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 | 77% |
| 70 to 90 | Confident: backbone generally right | 19% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Export receptor for importin alpha (SRP1). Mediates importin-alpha re-export from the nucleus to the cytoplasm after import substrates have been released into the nucleoplasm
Binds with high affinity to SRP1 only in the presence of RanGTP. The complex is dissociated by the RanGTP-binding protein YRB1
