Biological function summary
The protein plays a central role in the maintenance of lipid homeostasis and modulation of inflammatory responses. LXR beta acts within a complex system that also involves other nuclear receptors and co-regulators to effectively control gene transcription. Through its activity LXR beta impacts cholesterol efflux fatty acid synthesis and inflammatory gene expression. It helps preserve cellular lipid balance a critical factor for normal cellular function and overall organism health.
Pathways
LXR beta plays a significant role in the cholesterol metabolism and lipid homeostasis pathways. It activates the transcription of genes like ABCA1 and ABCG1 important for cholesterol efflux in macrophages and other cell types. LXR beta interacts closely with proteins such as SREBP-1c (Sterol Regulatory Element Binding Protein 1c) and RXR which are integral to lipid metabolism pathways. By modulating these pathways LXR beta contributes to reverse cholesterol transport reducing cholesterol overload in cells.

General info
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 phosphatidylcholines of ER membranes, increasing membrane dynamics and enabling triacylglycerols transfer to nascent very low-density lipoprotein (VLDL) particles (By similarity). Via LPCAT3 also counteracts lipid-induced ER stress response and inflammation, likely by modulating SRC kinase membrane compartmentalization and limiting the synthesis of lipid inflammatory mediators (By similarity). Plays an anti-inflammatory role during the hepatic acute phase response by acting as a corepressor : inhibits the hepatic acute phase response by preventing dissociation of the N-Cor corepressor complex (PubMed : 20159957).
Sequence similarities
Belongs to the nuclear hormone receptor family. NR1 subfamily.
Post-translational modifications
Sumoylated by SUMO2 at Lys-409 and Lys-447 during the hepatic acute phase response, leading to promote interaction with GPS2 and prevent N-Cor corepressor complex dissociation.
