Human PXR LBD

PXR is a xenobiotic-activated member of the nuclear receptor superfamily of transcription factors. PXR is involved in transcriptional induction of hepatic xenobiotic-catabolizing cytochrome 3A enzymes, playing a fundamental role in protecting body tissues from toxic bile acids. PXR is almost exlcusively expressed in the gastrointestinal system (stomach, duodenum, jejunum, ileum, colon and gall bladder) and liver, with lower levels in the kidney and ovary. PXR dysfunction is associated with immune disorders (sclerosing cholangitis, inflammatory bowel disease) and biliary primary cirrhosis.
