PPARα LBD (human recombinant)
Cayman Chemical Item Number 10009088
Peroxisome Proliferator-activated Receptor α Ligand Binding Domain
recombinant His-tagged protein purified from E. coli
Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear receptor family of ligand activated transcription factors that heterodimerize with retinoic acid like receptor to regulate gene expression and differentiation.1 The PPAR family of nuclear hormone receptors consists of three subtypes encoded by separate genes: PPARα, PPARδ (also referred to as hNUC1, PPARβ, or FAAR), and PPARγ. Among them PPARα is highly expressed in tissues displaying a high catabolic rate of fatty acids such as the liver, skeletal muscles, brown fat, heart, kidneys, and cells of artherosclerotic lesions.2 Fatty acids, NSAIDs, prostaglandins, leukotriene B4, WY 14643, and hypolipidemic drugs are PPARα ligands.3,4,5 PPARα transcriptionally regulates a variety of genes involved in fatty acid metabolism and oxidation, such as acyl-CoA oxidase, enol-CoA hydratase, medium chain fatty acyl-CoA dehydrogenase, fatty acid transport protein, and cytochrome P450 4A isozymes.6,7 Cayman’s PPARα LBD (amino acids 170-430 of full length human PPARα) has been expressed and purified from E. coli. The purity was determined using gel electrophoresis followed by coomassie staining and western blot analysis. Functionality of PPARα LBD was tested using a fluorescent ligand binding assay.
