The mean pLDDT of this model is 77.8 (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 | 49% |
| 70 to 90 | Confident: backbone generally right | 25% |
| 50 to 70 | Low: treat with caution | 9% |
| Below 50 | Very low: often disordered regions | 18% |
What pLDDT means and how to read it
Adapter protein that binds to and probably organizes the subcellular localization of a variety of membrane proteins. May link various receptors to the actin cytoskeleton and the dystrophin glycoprotein complex
Monomer and homodimer (Probable). Interacts with the other members of the syntrophin family SNTA1 and SNTB2; with the sodium channel proteins SCN4A and SCN5A (By similarity). Interacts with the viral HTLV-1 TAX protein and with dystrophin protein DMD and related proteins DTNA and UTRN. Interacts with DTNB (By similarity)
Cell membrane, sarcolemma, Cell junction, Cytoplasm, cytoskeleton
