The mean pLDDT of this model is 84.5 (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 | 58% |
| 70 to 90 | Confident: backbone generally right | 22% |
| 50 to 70 | Low: treat with caution | 14% |
| Below 50 | Very low: often disordered regions | 6% |
What pLDDT means and how to read it
Inhibits the transcriptional activation activity of the cone-rod homeobox CRX (By similarity). May participate in the regulation of visual phototransduction or in the integration of photoreceptor metabolism
Interacts with CRX (By similarity). Forms a complex with the beta and gamma subunits of the GTP-binding protein, transducin
Cytoplasm, cytosol, Nucleus, Cell projection, cilium, photoreceptor outer segment, Photoreceptor inner segment
