The mean pLDDT of this model is 86.6 (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 | 68% |
| 70 to 90 | Confident: backbone generally right | 18% |
| 50 to 70 | Low: treat with caution | 14% |
| Below 50 | Very low: often disordered regions | 1% |
What pLDDT means and how to read it
SNARE involved in vesicular transport from the late endosomes to the trans-Golgi network
Interacts with POPDC1 (via the C-terminus cytoplasmic tail). Interacts with BCAP31; involved in VAMP3 export from the endoplasmic reticulum (By similarity). Interacts with BAIAP3; this interaction is increased in the presence of calcium (By similarity). Interacts with PICALM (By similarity)
