The mean pLDDT of this model is 75.8 (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 | 27% |
| 70 to 90 | Confident: backbone generally right | 49% |
| 50 to 70 | Low: treat with caution | 6% |
| Below 50 | Very low: often disordered regions | 18% |
What pLDDT means and how to read it
Microtubule-dependent motor required for slow axonal transport of neurofilament proteins (NFH, NFM and NFL). Can induce formation of neurite-like membrane protrusions in non-neuronal cells in a ZFYVE27-dependent manner. The ZFYVE27-KIF5A complex contributes to the vesicular transport of VAPA, VAPB, SURF4, RAB11A, RAB11B and RTN3 proteins in neurons (By similarity). Required for anterograde axonal transportation of MAPK8IP3/JIP3 which is essential for MAPK8IP3/JIP3 function in axon elongation (PubMed:23576431)
Oligomer composed of two heavy chains and two light chains. Interacts with GRIP1. Interacts with FMR1 (via C-terminus); this interaction is increased in a mGluR-dependent manner. Interacts with BORCS5. Interacts with ZFYVE27. Interacts with VAPA, VAPB, SURF4, RAB11A (GDP-bound form), RAB11B (GDP-bound form) and RTN3 in a ZFYVE27-dependent manner. Interacts with BICD2. Interacts with DTNB…
