    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human FXR/NR1H4 protein.

    Background

    The farnesoid X receptor (FXR/NR1H4) is a member of the nuclear hormone receptor superfamily and is a master regulator of bile acid synthesis. FXR/NR1H4 heterodimerizes with RXR-alpha upon activation by bile acids, which begins a regulatory cascade involving SHP and LRH-1 to control lipid homeostasis (1-5). FXR/NR1H4 has also been shown to be a critical regulator of glucose homeostasis (6,7). In addition to directly regulating genes, FXR/NR1H4 also plays a post transcriptional role in bile acid metabolism by transcribing the RNA-binding protein ZFP36L1, which in turn downregulates the key enzyme Cyp7a1 (8). Mutations in human FXR/NR1H4 have been shown to cause cholestasis and liver disease in neonatal patients (9). FXR/NR1H4 can also control Lgr5+ intestinal stem cell proliferation and its upregulation has been shown to inhibit colorectal cancer progression (10-12). Agonists against FXR/NR1H4 are being evaluated for various liver diseases and diabetes (13-16).
