The mean pLDDT of this model is 68.1 (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 | 40% |
| 70 to 90 | Confident: backbone generally right | 13% |
| 50 to 70 | Low: treat with caution | 9% |
| Below 50 | Very low: often disordered regions | 38% |
What pLDDT means and how to read it
Calcium/calmodulin-dependent protein kinase which phosphorylates cmk-1 (PubMed:10336483, PubMed:10428833, PubMed:12231504, PubMed:29875264). Component of a calcium-triggered signaling cascade involved in CRE-mediated transcriptional activation, probably through cmk-1-mediated crh-1/CREB phosphorylation (PubMed:12231504). Plays a role in salt-avoidance learning behavior via the phosphorylation of cmk-1 (PubMed:29875264)
