The mean pLDDT of this model is 86.6 (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 | 73% |
| 70 to 90 | Confident: backbone generally right | 7% |
| 50 to 70 | Low: treat with caution | 14% |
| Below 50 | Very low: often disordered regions | 6% |
What pLDDT means and how to read it
Adapter molecule that plays a key role in the activation of pro-inflammatory NF-kappa-B signaling following detection of bacterial pathogen-associated molecular pattern metabolites (PAMPs) (PubMed:12566447, PubMed:15492226, PubMed:26068852, PubMed:28222186, PubMed:28877472, PubMed:30111836). Promotes activation of an innate immune response by inducing the oligomerization and polyubiquitination of TRAF6, which leads to the activation of TAK1 and IKK through a proteasome-independent mechanism (PubMed:15492226, PubMed:26068852). TIFA-dependent innate immune response is triggered by ADP-D-glycero-beta-D-manno-heptose (ADP-Heptose), a potent PAMP present in all Gram-negative and some…
Homooligomer; homooligomerizes following phosphorylation at Thr-9 (PubMed:12566447, PubMed:22566686, PubMed:26068852, PubMed:26389808). Interacts with IRAK1, TRAF2 and TRAF6 (PubMed:12566447). Interacts with TIFAB; binding to TIFAB inhibits TRAF6 activation, possibly by inducing a conformational change in TIFA (PubMed:15047173). Interacts with ZCCHC11; binding to ZCCHC11 suppresses the…
