The mean pLDDT of this model is 88.4 (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 | 75% |
| 70 to 90 | Confident: backbone generally right | 8% |
| 50 to 70 | Low: treat with caution | 17% |
| Below 50 | Very low: often disordered regions | 0% |
What pLDDT means and how to read it
Alpha-beta TR is a heterodimer composed of an alpha and beta chain; disulfide-linked. The alpha-beta TR is associated with the transmembrane signaling CD3 coreceptor proteins to form the TR-CD3 (TcR or TCR). The assembly of alpha-beta TR heterodimers with CD3 occurs in the endoplasmic reticulum where a single alpha-beta TR heterodimer associates with one CD3D-CD3E heterodimer, one CD3G-CD3E…
