The mean pLDDT of this model is 83.1 (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 | 70% |
| 70 to 90 | Confident: backbone generally right | 12% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 16% |
What pLDDT means and how to read it
May function as an adapter linking the Par3 complex to the GPSM1/GPSM2 complex (PubMed:16458856). Involved in spindle orientation during mitosis. May regulate cell proliferation and differentiation in the developing nervous system. May play a role in the asymmetric division of fibroblasts and participate in the process of stratification of the squamous epithelium (By similarity)
Interacts with ALS2CR19/PAR3B and F2RL2/PAR3 (PubMed:16458856). Interacts with GPSM1/AGS3 and GPSM2/LGN (via TPR repeat region) (PubMed:16458856, PubMed:22074847). Identified in a complex with GPSM2 and F2RL2 (PubMed:16458856)
