The mean pLDDT of this model is 76.3 (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 | 50% |
| 70 to 90 | Confident: backbone generally right | 14% |
| 50 to 70 | Low: treat with caution | 12% |
| Below 50 | Very low: often disordered regions | 24% |
What pLDDT means and how to read it
May play a role in regulating the integrity of microtubules possibly by influencing their stability. Involved in an anchoring mechanism to maintain tea2 and tip1 at growing microtubule ends. Strongly stimulates the ATPase activity of tea2
Interacts with tea2
Cytoplasm, cytoskeleton
