The mean pLDDT of this model is 86.5 (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 | 48% |
| 70 to 90 | Confident: backbone generally right | 44% |
| 50 to 70 | Low: treat with caution | 5% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Required for vesicular transport between the endoplasmic reticulum and the Golgi apparatus (PubMed:8455721). Together with GNA12 promotes CDH5 localization to plasma membrane (By similarity)
Interacts with PRKCABP, and disrupts the interaction between GRIA2 and PRKCABP, leading to the internalization of GRIA2. Found in a complex with VAMP8. Component of a SNARE-like complex that contains at least ZW10, USE1L, RINT1, STX18 and NAPA/SNAP-alpha. Interacts with VTI1A. Interacts with STX12. Interacts with GNA12 (via N-terminus); the interaction promotes CDH5 localization to plasma membrane
