The mean pLDDT of this model is 74.6 (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 | 40% |
| 70 to 90 | Confident: backbone generally right | 27% |
| 50 to 70 | Low: treat with caution | 9% |
| Below 50 | Very low: often disordered regions | 24% |
What pLDDT means and how to read it
Receptor for somatostatin-14 and -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase
Homodimer and heterodimer with SSTR2. Heterodimerization with SSTR2 inactivates SSTR3 receptor function (By similarity)
