The mean pLDDT of this model is 62.0 (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 | 1% |
| 70 to 90 | Confident: backbone generally right | 22% |
| 50 to 70 | Low: treat with caution | 66% |
| Below 50 | Very low: often disordered regions | 11% |
What pLDDT means and how to read it
Stimulates feeding and grooming behavior, metabolic rate and locomotor activity and increases blood pressure. May have orexigenic activity. May promote aldosterone secretion by the adrenal gland
