The mean pLDDT of this model is 81.3 (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 | 6% |
| 70 to 90 | Confident: backbone generally right | 82% |
| 50 to 70 | Low: treat with caution | 10% |
| 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. Component of the spindle pole body (SPB) required for the proper execution of spindle pole body (SPB) duplication
Component of the SPC110 complex containing at least CMD1, SPC29, SPC42 and SCP110. Interacts with SPC110
Cytoplasm, cytoskeleton, microtubule organizing center, spindle pole body
