The mean pLDDT of this model is 83.4 (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 | 51% |
| 70 to 90 | Confident: backbone generally right | 27% |
| 50 to 70 | Low: treat with caution | 15% |
| Below 50 | Very low: often disordered regions | 7% |
What pLDDT means and how to read it
Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Required for normal endocytic and biosynthetic traffic to the yeast vacuole
Component of the ESCRT-I complex (endosomal sorting complex required for transport I) which consists of STP22, VPS28, SRN2 and MVB12 in a 1:1:1:1 stoichiometry. Interacts with STP22 and MVB12
Cytoplasm, Endosome, Late endosome membrane
