Model confidence (pLDDT)

The mean pLDDT of this model is 68.4 (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.

What pLDDT means and how to read it

Function

Increases DNTT terminal deoxynucleotidyltransferase activity (in vitro) (PubMed:11473582). Also acts as a transcriptional regulator, binding to the consensus sequence 5'-GNTGCATG-3' following an AT-tract. Associates with RAB20 promoter and positively regulates its transcription. Binds DNA and nucleosomes; may recruit HDAC1 complexes to nucleosomes or naked DNA

Subunit structure

Monomer and homodimer (PubMed:11473582, PubMed:25653165). A minor proportion may form homotrimers (PubMed:11473582). Interacts with ZNF541 (PubMed:21573134). Interacts with the terminal deoxynucleotidyltransferase DNTT (PubMed:11473582, PubMed:16371131). Interacts with TRERF1 (PubMed:16371131, PubMed:21573134). Identified in a histone deacetylase complex that contains DNTTIP1, HDAC1 and MIDEAS;…
