The mean pLDDT of this model is 62.0 (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 | 25% |
| 70 to 90 | Confident: backbone generally right | 18% |
| 50 to 70 | Low: treat with caution | 8% |
| Below 50 | Very low: often disordered regions | 49% |
What pLDDT means and how to read it
Testis-specific chromatin protein that specifically binds histone H4 acetylated at 'Lys-5' and 'Lys-8' (H4K5ac and H4K8ac, respectively) and plays a key role in spermatogenesis (PubMed:12861021, PubMed:19794495, PubMed:22901802, PubMed:22922464). Required in late pachytene spermatocytes: plays a role in meiotic and post-meiotic cells by binding to acetylated histones at the promoter of specific meiotic and post-meiotic genes, facilitating their activation at the appropriate time. In the post-meiotic phase of spermatogenesis, binds to hyperacetylated histones and participates in their general removal from DNA (PubMed:22901802, PubMed:32726616). Also recognizes and binds a subset of…
Interacts with SMARCE1 (By similarity). Interacts with mRNA splicing machinery proteins SRSF2, DDX5, HNRNPK and TARDBP. Interacts with the acetylated N-terminus of histone H1, H2, H3 and H4. Interacts with P-TEFb components CDK9 and CCNT1/cyclin-T1
