The mean pLDDT of this model is 58.7 (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 | 38% |
| 50 to 70 | Low: treat with caution | 15% |
| Below 50 | Very low: often disordered regions | 47% |
What pLDDT means and how to read it
Endoplasmic reticulum (ER)-anchored autophagy regulator which exists in an inactive state under basal conditions but is activated following cellular stress (PubMed:34338405). When activated, induces ER fragmentation and mediates ER delivery into lysosomes through sequestration into autophagosomes via interaction with ATG8 family proteins (PubMed:34338405). Required for collagen quality control in a LIR motif-independent manner (By similarity)
Interacts with ATG8 family modifier proteins MAP1LC3A, MAP1LC3B, MAP1LC3C, GABARAP, GABARAPL1 and GABARAPL2 (PubMed:26040720, PubMed:34338405, PubMed:34854256). Shows higher affinity for GABARAPL1 than for MAP1LC3B (PubMed:34854256). Interacts with CANX (PubMed:34338405)
