[[http://www.uniprot.org/uniprot/PPARD_HUMAN PPARD_HUMAN]] Ligand-activated transcription factor. Receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Has a preference for poly-unsaturated fatty acids, such as gamma-linoleic acid and eicosapentanoic acid. Once activated by a ligand, the receptor binds to promoter elements of target genes. Regulates the peroxisomal beta-oxidation pathway of fatty acids. Functions as transcription activator for the acyl-CoA oxidase gene.

| + | Iloprost is a prostacyclin analog that has been used to treat many vascular conditions. Peroxisome proliferator-activated receptors (PPARs) are ligand-regulated transcription factors with various important biological effects such as metabolic and cardiovascular physiology. Here, we report the crystal structures of the PPARalpha ligand-binding domain and PPARdelta ligand-binding domain bound to iloprost, thus providing unambiguous evidence for the direct interaction between iloprost and PPARs and a structural basis for the recognition of PPARalpha/delta by this prostacyclin analog. In addition to conserved contacts for all PPARalpha ligands, iloprost also initiates several specific interactions with PPARs using its unique structural groups. Structural and functional studies of receptor-ligand interactions reveal strong functional correlations of the iloprost-PPARalpha/delta interactions as well as the molecular basis of PPAR subtype selectivity toward iloprost ligand. As such, the structural mechanism may provide a more rational template for designing novel compounds targeting PPARs with more favorable pharmacologic impact based on existing iloprost drugs. | ||
