The mean pLDDT of this model is 87.5 (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 | 42% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 2% |
What pLDDT means and how to read it
Required for vesicular transport between the endoplasmic reticulum and the Golgi apparatus. Together with GNA12 promotes CDH5 localization to plasma membrane
Interacts with PRKCABP, and disrupts the interaction between GRIA2 and PRKCABP, leading to the internalization of GRIA2 (PubMed:11931741). Found in a complex with VAMP8 (PubMed:9614193). Component of a SNARE-like complex that contains at least ZW10, USE1L, RINT1, STX18 and NAPA/SNAP-alpha (By similarity). Interacts with VTI1A (By similarity). Interacts with STX12 (PubMed:9507000). Interacts with…
