What pLDDT means and how to read it

Function

Nuclear receptor that exhibits a ligand-dependent transcriptional activation activity (PubMed:25661920). Binds preferentially to double-stranded oligonucleotide direct repeats having the consensus half-site sequence 5'-AGGTCA-3' and 4-nt spacing (DR-4). Regulates cholesterol uptake through MYLIP-dependent ubiquitination of LDLR, VLDLR and LRP8; DLDLR and LRP8. Interplays functionally with RORA for the regulation of genes involved in liver metabolism (By similarity). Induces LPCAT3-dependent phospholipid remodeling in endoplasmic reticulum (ER) membranes of hepatocytes, driving SREBF1 processing and lipogenesis (By similarity). Via LPCAT3, triggers the incorporation of arachidonate into…

Subunit structure

Forms a heterodimer with RXR. Interacts with CCAR2 (via N-terminus) in a ligand-independent manner (PubMed:25661920). Interacts (when sumoylated) with GPS2; interaction with GPS2 onto hepatic acute phase protein promoters prevents N-Cor corepressor complex dissociation (PubMed:20159957). Interacts with ABCA12 and ABCA1; this interaction is required for ABCA1 localization to the cell surface and…
