The mean pLDDT of this model is 73.8 (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 | 33% |
| 70 to 90 | Confident: backbone generally right | 36% |
| 50 to 70 | Low: treat with caution | 10% |
| Below 50 | Very low: often disordered regions | 21% |
What pLDDT means and how to read it
Inhibits calcineurin-dependent transcriptional responses by binding to the catalytic domain of calcineurin A (PubMed:12809556). Could play a role during central nervous system development (By similarity)
Interacts with RAF1 (PubMed:15935327). Interacts with PPP3CA and PPP3R1 (PubMed:12809556)
