The mean pLDDT of this model is 70.4 (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 | 28% |
| 70 to 90 | Confident: backbone generally right | 22% |
| 50 to 70 | Low: treat with caution | 32% |
| Below 50 | Very low: often disordered regions | 19% |
What pLDDT means and how to read it
RNA-binding RNA annealing protein. May have a role in pre-mRNA metabolism. Component the TREX complex, which operates in coupling transcription elongation to mRNA export
Component of the transcription/export (TREX) complex, which is at least is formed of SUB2, TEX1 and YRA1 and the THO complex composed of HPR1, MFT1, THO2 and THP1. Interacts with RDS3 and YRA2
