Background: FXR/NR1H4

Farnesoid X-activated Receptor (FXR, HRR-1, BAR, RIP14; NR1H4) is a member of the Orphan Nuclear Receptor family. FXR is expressed in the liver, intestinal villi, renal tubes and adrenal cortex. FXR is a global regulator of bile acid metabolism. Two genes, cholesterol 7a-hydroxylase (CYP7A1) and IBABP (Ileal Bile Acid Binding Protein), which are implicated in bile acid biosynthesis and recycling, respectively, are target genes of FXR. FXR is shown to be transcriptionally activated by farnesol metabolites such as farnesol itself and juvenile hormone III. FXR binds to DNA only as a heterodimer with Retinoid X Receptor (RXR).
