The mean pLDDT of this model is 75.6 (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 | 38% |
| 70 to 90 | Confident: backbone generally right | 14% |
| 50 to 70 | Low: treat with caution | 46% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
May be involved in forming the receptor site for cardiac glycoside binding or may modulate the transport function of the sodium ATPase
Regulatory subunit of the sodium/potassium-transporting ATPase which is composed of a catalytic alpha subunit, an auxiliary non-catalytic beta subunit and an additional regulatory subunit
