The mean pLDDT of this model is 66.4 (low 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 | 38% |
| 70 to 90 | Confident: backbone generally right | 14% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 43% |
What pLDDT means and how to read it
Ca(2+)/calmodulin-dependent kinase that phosphorylates the regulatory light chain (RLC) of sarcomeric myosin in skeletal and cardiac muscle. Phosphorylation of RLC promotes displacement of myosin cross-bridges from the thick filament backbone toward actin-containing thin filaments, increasing the probability of cross-bridge entry into force-generating states and thereby potentiating contractile force at submaximal Ca(2+) concentrations
