The mean pLDDT of this model is 91.4 (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 | 80% |
| 70 to 90 | Confident: backbone generally right | 12% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 7% |
What pLDDT means and how to read it
May regulate a number of protein-protein interactions by competing for PDZ domain binding sites. Binds CTNNB1 and may thereby act as an inhibitor of the Wnt signaling pathway. Competes with LIN7A for KCNJ4 binding, and thereby promotes KCNJ4 internalization. May play a role in the Rho signaling pathway (By similarity)
Interacts (via its PDZ domain) with GLS2. Interacts (via its PDZ domain) with RTKN (via the C-terminal region); this interaction facilitates Rho-mediated activation of the FOS serum response element (SRE). Interacts (via PDZ domain) with ARHGEF16. Interacts (via PDZ domain) with KCNJ4 (via C-terminus). Competes with LIN7A for KCNJ4 binding (By similarity). Interacts (via its PDZ domain) with…
