Farnesoid X receptor (FXR, NR1H4) is a member of the nuclear hormone receptor superfamily. These nuclear hormone receptors are ligand-activated transcription factors that elicit their actions by binding to hormone response elements (HREs) in the promoters of target genes and regulating transcription in response to lipophilic ligands.AcceGen Biotech now offers Human FXR Luciferase Reporter Cell Line-HepG2 to the research community. This high-quality stable cell lines will facilitate further molecular studies of FXR pathway its functions.
