The mean pLDDT of this model is 79.2 (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 | 36% |
| 70 to 90 | Confident: backbone generally right | 37% |
| 50 to 70 | Low: treat with caution | 20% |
| Below 50 | Very low: often disordered regions | 7% |
What pLDDT means and how to read it
Substrate recognition component of the SKP1-CUL1-F-box protein E3 ubiquitin-protein ligase complex SCF(UCC1) which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed:10582239, PubMed:25982115). The SCF(UCC1) complex acts as a metabolic switch for the glyoxylate cycle and regulates the level of CIT2 protein to maintain citrate homeostasis (PubMed:25982115)
Component of the SCF(UCC1) E3 ubiquitin-protein ligase complex composed of CDC53, SKP1, RBX1 and UCC1 (PubMed:11283612, PubMed:14747994). Interacts with CIT2 (PubMed:25982115)
