The mean pLDDT of this model is 74.8 (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 | 34% |
| 70 to 90 | Confident: backbone generally right | 37% |
| 50 to 70 | Low: treat with caution | 11% |
| Below 50 | Very low: often disordered regions | 18% |
What pLDDT means and how to read it
Component of the nexin-dynein regulatory complex (N-DRC) a key regulator of ciliary/flagellar motility which maintains the alignment and integrity of the distal axoneme and regulates microtubule sliding in motile axonemes (By similarity). Plays a critical role in the assembly of N-DRC and also stabilizes the assembly of multiple inner dynein arms and radial spokes (PubMed:23354437, PubMed:34169321). Coassembles with DRC2 to form a central scaffold needed for assembly of the N-DRC and its attachment to the outer doublet microtubules (PubMed:23354437)
Component of the nexin-dynein regulatory complex (N-DRC). Interacts with DRC2, DRC3, DRC4 and DRC5 (PubMed:34169321)
