The mean pLDDT of this model is 89.8 (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 | 70% |
| 70 to 90 | Confident: backbone generally right | 23% |
| 50 to 70 | Low: treat with caution | 4% |
| Below 50 | Very low: often disordered regions | 3% |
What pLDDT means and how to read it
Involved in mRNA export coupled transcription activation by association with both the TREX-2 and the SAGA complexes. At the promoters, SAGA is required for recruitment of the basal transcription machinery. It influences RNA polymerase II transcriptional activity through different activities such as TBP interaction and promoter selectivity, interaction with transcription activators, and chromatin modification through histone acetylation and deubiquitination. Within the SAGA complex, participates to a subcomplex required for deubiquitination of H2B and for the maintenance of steady-state H3 methylation levels. The TREX-2 complex functions in docking export-competent ribonucleoprotein…
Component of the nuclear pore complex (NPC)-associated TREX-2 complex (transcription and export complex 2), composed of at least SUS1, SAC3, THP1, SEM1, and CDC31. TREX-2 contains 2 SUS1 chains. The TREX-2 complex interacts with the nucleoporin NUP1. Component of the 1.8 MDa SAGA transcription coactivator-HAT complex. SAGA is built of 5 distinct domains with specialized functions. Within the…
