The mean pLDDT of this model is 63.2 (low 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 | 0% |
| 70 to 90 | Confident: backbone generally right | 43% |
| 50 to 70 | Low: treat with caution | 32% |
| Below 50 | Very low: often disordered regions | 25% |
What pLDDT means and how to read it
Acts as a receptor for reticulophagy. Directs autophagic sequestration of folded tubules/sheets derived from the cortical endoplasmic reticulum (cER) and the cytoplasmic endoplasmic reticulum (cytoER) into autophagosomes. Is not required for the cytoplasm-to-vacuole targeting pathway, mitophagy, pexophagy, and non-selective autophagy
Interacts with ATG8 and ATG11
