The mean pLDDT of this model is 85.0 (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 | 62% |
| 70 to 90 | Confident: backbone generally right | 24% |
| 50 to 70 | Low: treat with caution | 7% |
| Below 50 | Very low: often disordered regions | 8% |
What pLDDT means and how to read it
Component of a complex required to localize phosphatidylinositol 4-kinase (PI4K) to the plasma membrane. The complex acts as a regulator of phosphatidylinositol 4-phosphate (PtdIns(4)P) synthesis. In the complex, plays a central role in bridging PI4KA to EFR3B and HYCC1, via direct interactions (PubMed:26571211)
Component of a phosphatidylinositol 4-kinase (PI4K) complex, composed of PI4KA, EFR3 (EFR3A or EFR3B), TTC7 (TTC7A or TTC7B) and HYCC (HYCC1 or HYCC2) (PubMed:23229899). Interacts with PI4KA, interaction is direct (PubMed:26571211). Interacts with EFR3 (EFR3A or EFR3B), interaction is direct (PubMed:26571211). Interacts with HYCC (HYCC1 or HYCC2), interaction is direct (PubMed:26571211).…
