The mean pLDDT of this model is 53.6 (low 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 | 6% |
| 70 to 90 | Confident: backbone generally right | 10% |
| 50 to 70 | Low: treat with caution | 30% |
| Below 50 | Very low: often disordered regions | 53% |
What pLDDT means and how to read it
Plays a role as a transcription factor (PubMed:22132193, PubMed:25355627). Mediates positive transcriptional regulation of several chaperone genes during the heat shock response in a HSF1-dependent manner (PubMed:25355627, PubMed:25816751). Mediates negative transcriptional regulation of CDC25B expression (PubMed:22132193). Plays a role in the dephosphorylation of the heat shock factor HSF1 and ribosomal protein S6 kinase (S6K) by the protein phosphatase PP2A (PubMed:25816751, PubMed:26496226). Involved in the regulation of cell proliferation and resistance to thermal stress (PubMed:22132193, PubMed:25355627, PubMed:26496226). Involved in the cell cycle checkpoint and survival in response…
Monomer (PubMed:26496226). Homodimer (PubMed:26496226). Associates with the catalytic subunit of protein phosphatase PP2A (PubMed:25816751, PubMed:26496226). Interacts (via N- and C-terminal regions) with PPP2R2B (PubMed:25816751, PubMed:26496226). Interacts with PPP2R2A, PPP2R2C and PPP2R2D (PubMed:25816751). Interacts (via N-terminus) with RPS6KB1 (PubMed:26496226). Interacts (via central…
