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 | 12% |
| 50 to 70 | Low: treat with caution | 22% |
| Below 50 | Very low: often disordered regions | 16% |
What pLDDT means and how to read it
Regulatory protein which represses transcription and augments histone deacetylase activity of HDAC1. May have a potential role in tumor suppressor pathways through regulation of apoptosis. May function in the assembly and/or enzymatic activity of the mSin3A corepressor complex or in mediating interactions between the complex and other regulatory complexes (By similarity)
Interacts with HCFC1 (By similarity). Homodimer. Component of the SIN3 histone deacetylase (HDAC) corepressor complex. Interacts with SIN3A. Interaction with SIN3B enhances the interaction between SIN3B and HDAC1 to form a complex. Component of a mSin3A corepressor complex that contains SIN3A, SAP130, SUDS3/SAP45, ARID4B/SAP180, HDAC1 and HDAC2. Interacts with USP17L2; the interaction is direct…
