The mean pLDDT of this model is 92.8 (very high 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 | 84% |
| 70 to 90 | Confident: backbone generally right | 17% |
| 50 to 70 | Low: treat with caution | 0% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Mediates the uptake of pyruvate into mitochondria to maintain the balance between glycolysis and oxidative phosphorylation (PubMed:22628558, PubMed:26253029, PubMed:27317664, PubMed:40044865, PubMed:40101766). Plays an essential role in cellular metabolism (PubMed:40044865, PubMed:40101766)
Heterodimer; dimerises with MPC2 to form a functional mitochondrial pyruvate carrier (PubMed:26253029, PubMed:32403431, PubMed:40101766, PubMed:40044865, PubMed:35278701). May form a homodimer (PubMed:32403431)
