The mean pLDDT of this model is 89.4 (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 | 81% |
| 70 to 90 | Confident: backbone generally right | 8% |
| 50 to 70 | Low: treat with caution | 3% |
| Below 50 | Very low: often disordered regions | 8% |
What pLDDT means and how to read it
Regulates leading edge dynamics and cell motility in fibroblasts. May be involved in cytokinesis and signal transduction (By similarity)
Forms homooligomers, but does not form complexes with the other coronins. Interacts with Arp2/3 complex components, including ACTR2, ARPC1B and ARPC2. Binds actin (By similarity)
Cytoplasm, cytoskeleton, Cytoplasm, cytoskeleton, stress fiber
