The mean pLDDT of this model is 79.9 (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 | 50% |
| 70 to 90 | Confident: backbone generally right | 28% |
| 50 to 70 | Low: treat with caution | 7% |
| Below 50 | Very low: often disordered regions | 15% |
What pLDDT means and how to read it
Involved in the negative feedback regulation of the light-activated signaling cascade in photoreceptors through a calcium-mediated process. Interacts with tetrapeptide ligand located in C-terminal sequence of 3 key components of the visual cascade, tethering them and forming a macromolecular signaling phototransduction complex
Interacts with the C-terminus of trp, and with norpA and inaC to form the inaD signaling complex. Interacts with Fkbp59, which together with trpl, rhodopsin and calmodulin may also be part of the inaD complex
