The mean pLDDT of this model is 68.2 (low 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 | 3% |
| 70 to 90 | Confident: backbone generally right | 46% |
| 50 to 70 | Low: treat with caution | 31% |
| Below 50 | Very low: often disordered regions | 20% |
What pLDDT means and how to read it
Recruits TFIIH to the initiation complex and stimulates the RNA polymerase II C-terminal domain kinase and DNA-dependent ATPase activities of TFIIH. Both TFIIH and TFIIE are required for promoter clearance by RNA polymerase
Tetramer of two alpha and two beta chains (PubMed:1956398). Interacts with FACT subunit SUPT16H (PubMed:10792464). Interacts with ATF7IP (PubMed:19106100). Interacts with SND1 (PubMed:7651391). Part of TBP-based Pol II pre-initiation complex (PIC), in which Pol II core assembles with general transcription factors and other specific initiation factors including GTF2E1, GTF2E2, GTF2F1, GTF2F2,…
