    basic FUNCTION
  • acting as a tissue specific cofactor for RXRA, controlling lipid-inducible expression of APOE in macrophages and adipocytes
  • promoting cholesterol efflux into intestinal lumen via the ABCA1 transporter
  • coactivating CYP7A1
  • acting as a steroid and thyroid hormone receptor
  • acting as a transcription coactivator
  • nuclear oxysterol receptors with established roles in cholesterol, lipid, and carbohydrate metabolism
  • increases the transcription of genes involved in cholesterol efflux and disposal, such as ABCA1 (ATP-binding cassette transporter A1)
  • NR1H2, NR1H3 are negative regulators of cardiac growth and inflammation via suppressing NF-kappaB signalling in cardiomyocytes
  • induces the transcription of genes that protect cells from cholesterol overload
  • coactivator-binding surface of NR1H3, but not that of RXRA, is critically important for physical and functional interactions with NCOA1
  • new role for NR1H3 in phospholipid homeostasis (
  • NR1H2 and NR1H3 play a crucial role in control of insulin production and secretion in pancreatic beta-cells (
  • potentially NR1H2 as well as NR1H3 could play a crucial role in the regulation of energy homeostasis
  • NR1H2, NR1H3 play central roles in the transcriptional control of lipid metabolism
  • NR1H3 (liver X receptor) and PPARA are nuclear receptors that control the expression of genes involved in glucose and lipid homoeostasis
  • can act as an important inhibitor of TNFSF11-mediated osteoclast differentiation
  • is a ligand-activated transcription factor and plays an important role in regulation of lipid homoeostasis and inflammation
  • NR1H3, NR1H4 initiate formation of coated platelets
  • CELLULAR PROCESS nucleotide, transcription, regulation

  • NR0B1 is a corepressor of NR1H3, functioning as a negative regulator of lipogenic enzyme gene expression in liver
  • regulatory functions of AEBP1 on PPARG1 and NR1H3 transcriptional activity in the context of macrophage cholesterol homeostasis and inflammation
  • binds to the proximal regions of the PLIN1 and LIPE promoters
  • interaction of NR1H3 with CORO2A requires SUMOylation (possible involvement of deSUMOylating enzymes in negatively regulating NR1H3 repression functions)
  • CIDEA binds to liver X receptors (NR1H2, NR1H3) and regulates their activity (could therefore be of importance for the regulation of metabolic processes in human adipose tissue)
  • MID1IP1 is a mediator for stimulation of lipogenesis by NR1H2, NR1H3 activation in the liver
  • suppressive action of PIAS1 on NR1H2, NR1H3-activated gene expression programs, particularly in lipogenesis
  • ASXL2 increased NR1H3 activity through direct interaction in the presence of the ligand, but ASXL1 suppressed ligand-induced NR1H3 transcriptional activity
  • inhibits IFNG -induced biological responses, and IFNG is a new molecular target of NR1H3
  • UFM1 could suppress foam cell formation via the NR1H3-dependent pathway
  • AJUBA binds to the hinge and the ligand binding domains of NR1H3 via its C-terminal tandem LIM motifs and enhances NR1H3 target gene expression in liver cells
  • OSBPL2 binds to liver X receptor (NR1H3) and is required for nuclear NR1H3 expression
  • CRTC1 directly interferes with the expression of genes regulated by lipogenic transcription factors, most prominently liver x receptor alpha (NR1H3)
  • EEPD1 is a novel NR1H2, NR1H3-regulated gene in macrophages and likely it promotes cellular cholesterol efflux by controlling cellular levels and activity of ABCA1
  • SLC2A5 is regulated by NR1H3

    ANIMAL & CELL MODELS
  • Lxra -/- mice failed to induce transcription of the gene encoding cholesterol 7-alpha-hydroxylase. this defect was associated with a rapid accumulation of large amounts of cholesterol in the liver and the regulation of several other crucial lipid metabolizing genes was also altered(Peet, 98)
  • mice lacking Nr1h2, Nr1h3 manifested a breakdown in self-tolerance and developed autoantibodies and autoimmune glomerulonephritis
