The mean pLDDT of this model is 90.6 (very high 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 | 84% |
| 70 to 90 | Confident: backbone generally right | 6% |
| 50 to 70 | Low: treat with caution | 2% |
| Below 50 | Very low: often disordered regions | 7% |
What pLDDT means and how to read it
Microtubule inner protein (MIP) part of the dynein-decorated doublet microtubules (DMTs) in cilia and flagellar axoneme (PubMed:15340058, PubMed:37295417, PubMed:37865089, PubMed:37989994). Plays a key role in the assembly or attachment of the inner dynein arm to microtubules in sperm flagella and tracheal cilia (PubMed:15340058). Forms filamentous polymers in the walls of ciliary and flagellar microtubules (PubMed:15340058)
Microtubule inner protein component of sperm flagellar doublet microtubules (PubMed:37295417, PubMed:37865089, PubMed:37989994). May interact with CCDC172 (PubMed:24394471)
