The mean pLDDT of this model is 84.7 (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 | 38% |
| 70 to 90 | Confident: backbone generally right | 52% |
| 50 to 70 | Low: treat with caution | 9% |
| Below 50 | Very low: often disordered regions | 2% |
What pLDDT means and how to read it
Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases
Interacts (in the presence of Ca(2+)) with pde-1, madf-3, rpl-7A, tax-6, efk-1, npp-1, obr-4, sos-1, akt-1, unc-13, tag-196, ugt-48, nmy-2, F27D4.4, ddx-23, efa-6 and R11H6.4
