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. Decreases expression of NPC1L1 once activated by a ligand.<ref>PMID:1333051</ref> <ref>PMID:15604518</ref> | [[http://www.uniprot.org/uniprot/PPARD_HUMAN PPARD_HUMAN]] Ligand-activated transcription factor.

== Publication Abstract from PubMed == | |||
The peroxisome proliferator-activated receptor (PPAR) family comprises three subtypes: PPARalpha, PPARgamma, and PPARdelta. PPARdelta transcriptionally modulates lipid metabolism and the control of energy homeostasis; therefore, PPARdelta agonists are promising agents for treating a variety of metabolic disorders. In the present study, we develop a panel of rationally designed PPARdelta agonists. The modular motif affords efficient syntheses using building blocks optimized for interactions with subtype-specific residues in the PPARdelta ligand-binding domain (LBD). A combination of atomic-resolution protein X-ray crystallographic structures, ligand-dependent LBD stabilization assays, and cell-based transactivation measurements delineate structure-activity relationships (SARs) for PPARdelta-selective targeting and structural modulation. We identify key ligand-induced conformational transitions of a conserved tryptophan side chain in the LBD that trigger reorganization of the H2'-H3 surface segment of PPARdelta. The subtype-specific conservation of H2'-H3 sequences suggests that this architectural remodeling constitutes a previously unrecognized conformational switch accompanying ligand-dependent PPARdelta transcriptional regulation. | |||
