Protein function

Ligand-activated transcription factor. Receptor for bile acids (BAs) such as chenodeoxycholic acid (CDCA), lithocholic acid, deoxycholic acid (DCA) and allocholic acid (ACA). Plays a essential role in BA homeostasis through the regulation of genes involved in BA synthesis, conjugation and enterohepatic circulation. Also regulates lipid and glucose homeostasis and is involved innate immune response . The FXR-RXR heterodimer binds predominantly to farnesoid X receptor response elements (FXREs) containing two inverted repeats of the consensus sequence 5′-AGGTCA-3′ in which the monomers are spaced by 1 nucleotide (IR-1) but also to tandem repeat DR1 sites with lower affinity, and can be activated by either FXR or RXR-specific ligands. It is proposed that monomeric nuclear receptors such as NR5A2/LRH-1 bound to coregulatory nuclear responsive element (NRE) halfsites located in close proximity to FXREs modulate transcriptional activity (By similarity). In the liver activates transcription of the corepressor NR0B2 thereby indirectly inhibiting CYP7A1 and CYP8B1 (involved in BA synthesis) implicating at least in part histone demethylase KDM1A resulting in epigenomic repression, and SLC10A1/NTCP (involved in hepatic uptake of conjugated BAs). Activates transcription of the repressor MAFG (involved in regulation of BA synthesis) (By similarity). Activates transcription of SLC27A5/BACS and BAAT (involved in BA conjugation), ABCB11/BSEP (involved in bile salt export) by directly recruiting histone methyltransferase CARM1, and ABCC2/MRP2 (involved in secretion of conjugated BAs) and ABCB4 (involved in secretion of phosphatidylcholine in the small intestine) . Activates transcription of SLC27A5/BACS and BAAT (involved in BA conjugation), ABCB11/BSEP (involved in bile salt export) by directly recruiting histone methyltransferase CARM1, and ABCC2/MRP2 (involved in secretion of conjugated BAs) and ABCB4 (involved in secretion of phosphatidylcholine in the small intestine) . In the intestine activates FGF19 expression and secretion leading to hepatic CYP7A1 repression . The function also involves the coordinated induction of hepatic KLB/beta-klotho expression (By similarity). Regulates transcription of liver UGT2B4 and SULT2A1 involved in BA detoxification; binding to the UGT2B4 promoter seems to imply a monomeric transactivation independent of RXRA . Modulates lipid homoestasis by activating liver NR0B2/SHP-mediated repression of SREBF1 (involved in de novo lipogenesis), expression of PLTP (involved in HDL formation), SCARB1 (involved in HDL hepatic uptake), APOE, APOC1, APOC4, PPARA (involved in beta-oxidation of fatty acids), VLDLR and SDC1 (involved in the hepatic uptake of LDL and IDL remnants), and inhibiting expression of MTTP (involved in VLDL assembly . Increases expression of APOC2 (promoting lipoprotein lipase activity implicated in triglyceride clearance) . Transrepresses APOA1 involving a monomeric competition with NR2A1 for binding to a DR1 element . Also reduces triglyceride clearance by inhibiting expression of ANGPTL3 and APOC3 (both involved in inhibition of lipoprotein lipase) . Involved in glucose homeostasis by modulating hepatic gluconeogenesis through activation of NR0B2/SHP-mediated repression of respective genes. Modulates glycogen synthesis (inducing phosphorylation of glycogen synthase kinase-3) (By similarity). Modulates glucose-stimulated insulin secretion and is involved in insulin resistance . Involved in intestinal innate immunity. Plays a role in protecting the distal small intestine against bacterial overgrowth and preservation of the epithelial barrier (By similarity). Down-regulates inflammatory cytokine expression in several types of immune cells including macrophages and mononuclear cells . Mediates trans-repression of TLR4-induced cytokine expression; the function seems to require its sumoylation and prevents N-CoR nuclear receptor corepressor clearance from target genes such as IL1B and NOS2 . Involved in the TLR9-mediated protective mechanism in intestinal inflammation. Plays a anti-inflammatory role in liver inflammation; proposed to inhibit proinflammatory (but not antiapoptotic) NF-kappa-B signaling) (By similarity).; Isoform 1: Promotes transcriptional activation of target genes NR0B2/SHP (inducible by unconjugated CDCA), SLC51B/OSTB (inducible by unconjugated CDCA and DCA) and FABP6/IBAP; low activity for ABCB11/BSEP (inducible by unconjugated CDCA, DCA and ACA); not inducible by taurine- and glycine-amidated CDCA.; Isoform 2: Promotes transcriptional activation of target genes ABCB11/BSEP (inducible by unconjugated CDCA, DCA and ACA), NR0B2/SHP (inducible by unconjugated CDCA DCA and ACA), SLC51B/OSTB (inducible by unconjugated CDCA and DCA) and FABP6/IBAP; not inducible by taurine- and glycine-amidated CDCA.; Isoform 3: Promotes transcriptional activation of target genes NR0B2/SHP (inducible by unconjugated CDCA), SLC51B/OSTB (inducible by unconjugated CDCA and DCA) and IBAP; low activity for ABCB11/BSEP (inducible by unconjugated CDCA, DCA and ACA); not inducible by taurine- and glycine-amidated CDCA.; Isoform 4: Promotes transcriptional activation of target genes ABCB11/BSEP (inducible by unconjugated CDCA, ACA and DCA), NR0B2/SHP (inducible by unconjugated CDCA, ACA and DCA), SLC51B/OSTB (inducible by unconjugated CDCA and DCA) and FABP6/IBAP; most efficient isoform compared to isoforms 1 to 3; not inducible by taurine- and glycine-amidated CDCA.

Protein tissue specificity

Liver and hepatocyte-related cells express mainly FXRalpha1-type isoforms with isoform 3 and isoform 4 in approximative equal proportions. In intestine and kidney mainly FXRalpha2-type isoforms are expressed with isoform 1 and isoform 2 in approximative equal proportions. Expressed in pancreatic beta cells and macrophages.

Protein sequence and domain

Belongs to the nuclear hormone receptor family. NR1 subfamily.; Contains 1 nuclear receptor DNA-binding domain.

Protein post-translational modifications

Acetylated by EP300. Lys-227 as is the major acetylation site for EP300; the dynamicly regulated acetylation inhibits heterodimerization with RXRA and transactivation activity. Deacetylated by SIRT1.; Methylation may increase transactivation of target genes.; Phosphorylation by PKC/PRKCA increases transactivation activity by promoting association with PPARGC1A.; Sumoylated upon ligand binding.

Protein cellular localization

Nucleus .; Isoform 1: Nucleus .; Isoform 2: Nucleus .; Isoform 3: Nucleus .; Isoform 4: Nucleus .

Background

This gene encodes a ligand-activated transcription factor, which shares structural features in common with nuclear hormone receptor family, such as a DNA-binding domain that targets the receptor to specific DNA sequences, and a ligand-binding domain, which interacts directly with the ligand and contains a ligand-dependent transcriptional activation domain. This protein functions as a receptor for bile acids, and when bound to bile acids, regulates the expression of genes involved in bile acid synthesis and transport. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.
