Description General description Oxysterols receptor LXR-alpha (UniProt: Q62685; also known as Liver X receptor alpha, Nuclear receptor subfamily 1 group H member 3, RLD-1) is encoded by the Nr1h3 (also known as Lxra) gene in rat. Liver X receptors (LXRs) are members of the nuclear receptor superfamily that have been implicated in lipid homeostasis and glucose metabolism. Oxysterols, oxidized derivatives of cholesterol, are ligands for LXRs. LXRs act as cholesterol sensors; when cellular oxysterols accumulate as a result of increasing concentrations of cholesterol, LXR induces the transcription of genes that protect cells from cholesterol overload. LXRs bind to consensus elements (LXR response elements, LXREs) as heterodimers with isoforms of the retinoid X receptor (RXR). LXR-alpha is an important regulator of cholesterol and bile acid metabolism. It interacts with RXR and shifts RXR from its role as a silent DNA-binding partner to an active ligand-binding subunit in mediating retinoid responses through target genes defined by LXRES. In adults it is expressed in spleen, pituitary, lung, liver, and fat and a weaker expression is observed in several other tissues. LXR-alpha contains a transactivation domain (AF-1; aa 1-94) that is required for ligand-independent transactivation function; another transactivation domain (AF-2; aa 203-445) that is required for ligand-dependent transactivation function; and a ligand binding domain (aa 213-432).
