The mean pLDDT of this model is 78.0 (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 | 51% |
| 70 to 90 | Confident: backbone generally right | 25% |
| 50 to 70 | Low: treat with caution | 3% |
| Below 50 | Very low: often disordered regions | 21% |
What pLDDT means and how to read it
Subunit of heteromeric glycine-gated chloride channels. Plays an important role in the down-regulation of neuronal excitability. Contributes to the generation of inhibitory postsynaptic currents
Forms heteropentamers with glycin receptor alpha subunits. Heteropentamers with GLRA1 can be composed of two GLRA1 and three GLRB subunits, or three GLRA1 and two GLRB subunits, or four GLRA1 subunits and one GLRB subunit. Forms heteropentamers with GLRA2. Functional GLRB-GLRA2 heteropentamers contain four GLRA2 subunits and one GLRB subunit, although alternative subunit composition cannot be…
