The mean pLDDT of this model is 90.9 (very high 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 | 79% |
| 70 to 90 | Confident: backbone generally right | 15% |
| 50 to 70 | Low: treat with caution | 4% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Vesicular soluble NSF attachment protein receptor (v-SNARE) mediating vesicle docking and fusion to a specific acceptor cellular compartment (PubMed:9211930, PubMed:15215310). Functions in endoplasmic reticulum to Golgi transport; as part of a SNARE complex composed of GOSR1, GOSR2 and STX5 (By similarity). Functions in early/recycling endosome to TGN transport; as part of a SNARE complex composed of BET1L, GOSR1 and STX5 (PubMed:15215310). Has a S-palmitoyl transferase activity (PubMed:15479160, PubMed:15044687). Essential for the structural and functional organization of the Golgi apparatus (PubMed:32128853)
Identified in 2 different SNARE complexes; the first one composed of GOSR1, GOSR2 and STX5 and the second one composed of BET1L, GOSR1 and STX5
Cytoplasm, cytosol, Cytoplasmic vesicle membrane, Golgi apparatus membrane
