The mean pLDDT of this model is 72.6 (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 | 23% |
| 70 to 90 | Confident: backbone generally right | 50% |
| 50 to 70 | Low: treat with caution | 7% |
| Below 50 | Very low: often disordered regions | 21% |
What pLDDT means and how to read it
Calcium/calmodulin-regulated and magnesium-dependent enzyme that catalyzes the hydrolysis of ATP coupled with the transport of calcium out of the cell (PubMed:8530416). By regulating sperm cell calcium homeostasis, may play a role in sperm motility (By similarity)
Interacts with PDZD11 (PubMed:12763866). Interacts with SLC35G1 and STIM1 (PubMed:22084111). Interacts with calmodulin (PubMed:10493800, PubMed:2963820)
