LXRB Antibody / NR1H2

The liver X receptors, LXRA (NR1H3) and LXRB (NR1H2) form a subfamily of the nuclear receptor superfamily and are key regulators of macrophage function, controlling transcriptional programs involved in lipid homeostasis and inflammation. The inducible LXRA is highly expressed in liver, adrenal gland, intestine, adipose tissue, macrophages, lung, and kidney, whereas LXRB is ubiquitously expressed. Ligand-activated LXRs form obligate heterodimers with retinoid X receptors and regulate expression of target genes containing LXR response elements. LXRB can inhibit proliferation and induce apoptosis of cancer cells.
