What pLDDT means and how to read it

Function

Transcriptional corepressor that mediates the transcriptional repression activity of some nuclear receptors by promoting chromatin condensation, thus preventing access of the basal transcription (PubMed:10077563, PubMed:10097068, PubMed:18212045, PubMed:20812024, PubMed:22230954, PubMed:23911289). Acts by recruiting chromatin modifiers, such as histone deacetylases HDAC1, HDAC2 and HDAC3 (PubMed:22230954). Required to activate the histone deacetylase activity of HDAC3 (PubMed:22230954). Involved in the regulation BCL6-dependent of the germinal center (GC) reactions, mainly through the control of the GC B-cells proliferation and survival (PubMed:18212045, PubMed:23911289). Recruited by…

Subunit structure

Forms a large corepressor complex that contains SIN3A/B and histone deacetylases HDAC1 and HDAC2. This complex associates with the thyroid (TR) and the retinoid acid receptors (RAR) in the absence of ligand, and may stabilize their interaction with TFIIB. Interacts directly with RARA in the absence of ligand; the interaction represses RARA activity. Interacts (isoform SMRT) with HDAC10.…
