Western Blot: FXR Antibody [NB400-153] - Detection of FXR in HeLa nuclear extract using NB400-153. ECL 30 minute detection.
Immunocytochemistry/ Immunofluorescence: FXR Antibody [NB400-153] - FXR antibody was tested in HEK293 cells with DyLight 488 (green). Nuclei and alpha-tubulin were counterstained with DAPI (blue) and Dylight 550 (red).
This FXR antibody is useful for Immunocytochemistry/Immunofluorescence and Western blot analysis, where a band is seen at ~66 kDa. In ICC/IF nuclear and cytoplasmic staining was observed. The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
66 kDa. Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

FXR (farnesoid X receptor; NR1H4) belongs to nuclear receptor superfamily of ligand-activated transcription factors (NR1 subfamily) and acts as a receptor for bile acids such as chenodeoxycholic acid, lithocholic acid and deoxycholic acid. FXR is mainly expressed in liver, intestine, kidney, and adrenal glands. FXR heterodimerizes with retinoid X receptor (RXR alpha/NR2B1), associates with FXREs (FXR response elements) that are usually but not exclusively inverted repeat-1 (IR-1), and regulates the transcription of its target genes. FXR interacts with CARM1, SMARD1 and after activation by agonist binding, it interacts with a coactivator, NCOA1 or NCOA2. FXR has been shown to repress transcription of CYP7A1 (cholesterol 7-alpha-hydroxylase gene) through induction of NR0B2 or FGF19 expression, via two distinct mechanisms. FXR activates the intestinal bile acid-binding protein (IBABP) and transcription of bile salt export pump ABCB11 by directly recruiting histone methyltransferase CARM1 to this locus. Altogether, FXR is critical for maintaining a homeostasis in bile acid, cholesterol, lipoprotein, and triglyceride metabolism.
