The mean pLDDT of this model is 84.6 (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 | 43% |
| 70 to 90 | Confident: backbone generally right | 42% |
| 50 to 70 | Low: treat with caution | 12% |
| Below 50 | Very low: often disordered regions | 4% |
What pLDDT means and how to read it
In the presence of an appropriate stimulus, accelerates programmed cell death by binding to, and antagonizing the anti-apoptotic action of BCL2
Homodimer. Formation of the homodimer is zinc-dependent. Forms heterodimers with BCL2 and BCL2L1 isoform Bcl-X(L). Forms heterooligomers with BAX (By similarity). Interacts with BCL2A1 (PubMed:18462686). Interacts withRTL10/BOP (PubMed:18462686). Interacts with VDAC1 (By similarity). Interacts with GIMAP3/IAN4 and GIMAP5/IAN5 (PubMed:16509771)
