The mean pLDDT of this model is 90.9 (very high 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 | 74% |
| 70 to 90 | Confident: backbone generally right | 23% |
| 50 to 70 | Low: treat with caution | 1% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
C-mannosyltransferase that mediates C-mannosylation of tryptophan residues on target proteins such as unc-5 and mig-21. Mediates the attachment of alpha-mannose in C-C linkage to the C2 of the indole ring of tryptophan. C-mannosylation takes place in the endoplasmic reticulum and frequently found in thrombospondin (TSP) type-1 repeats and in the WSXWS motif of type I cytokine receptors. Required to orient neuroblasts QL and QR correctly on the anterior/posterior (A/P) axis: QL and QR are born in the same A/P position, but polarize and migrate left/right asymmetrically, QL migrates toward the posterior and QR migrates toward the anterior. Required with unc-40 to express mab-5 correctly in…
