The mean pLDDT of this model is 73.7 (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 | 22% |
| 70 to 90 | Confident: backbone generally right | 48% |
| 50 to 70 | Low: treat with caution | 10% |
| Below 50 | Very low: often disordered regions | 20% |
What pLDDT means and how to read it
Component of the gamma-tubulin ring complex (gTuRC) which mediates microtubule nucleation (PubMed:38305685, PubMed:38609661, PubMed:39321809, PubMed:9566967). The gTuRC regulates the minus-end nucleation of alpha-beta tubulin heterodimers that grow into microtubule protafilaments, a critical step in centrosome duplication and spindle formation (PubMed:38305685, PubMed:38609661, PubMed:39321809)
Component of the gamma-tubulin ring complex (gTuRC) consisting of TUBGCP2, TUBGCP3, TUBGCP4, TUBGCP5 and TUBGCP6 and gamma-tubulin TUBG1 or TUBG2 (PubMed:39321809, PubMed:38609661, PubMed:38305685). TUBGCP2, TUBGCP3, TUBGCP4, TUBGCP5 and TUBGCP6 assemble in a 5:5:2:1:1 stoichiometry; each is associated with a gamma-tubulin, thereby arranging 14 gamma-tubulins in a helical manner…
