The mean pLDDT of this model is 68.4 (low 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 | 37% |
| 70 to 90 | Confident: backbone generally right | 18% |
| 50 to 70 | Low: treat with caution | 7% |
| Below 50 | Very low: often disordered regions | 38% |
What pLDDT means and how to read it
May regulate the disassembly of focal adhesions. Did not bind receptor-like tyrosine phosphatases type 2A (By similarity)
Forms homodimers and heterodimers. Interacts with S100A4 in a Ca(2+)-dependent mode. Part of a cortical microtubule stabilization complex (CMSC) composed of KANK1, PPFIA1, PPFIBP1, ERC1/ELKS, PHLDB2/LL5beta, CLASPs, KIF21A and possibly additional interactors; within CMSCs KANK1 and PHLDB2/LL5beta seem to be the core components for recruiting microtubule-binding proteins KIF21A and CLASPs,…
