| - | + | [https://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. Decreases expression of NPC1L1 once activated by a ligand.<ref>PMID:1333051</ref> <ref>PMID:15604518</ref> | |

| - | High-resolution crystallographic structures of recombinant human peroxisome proliferator-activated receptor ligand-binding domain (isotype beta/delta) reveal a fatty acid in the binding site. Mass spectrometry confirmed the presence of C16:0, C16:1, C18:0 and C18:1 in a ratio of approximately 3:2:1:4 with 11, Z-octadecenoic acid (cis-vaccenic acid) identified as the predominant species. These are endogenous fatty acids acquired from the bacterial expression system, and serve to lock the ligand-binding domain into the activated conformation. A requirement for crystal growth, the additive n-heptyl-beta-d-glucopyranoside, binds near the activation function helix where recognition of co-activator proteins occurs. Our observations suggest potential physiological ligands for human PPAR-beta/delta and highlight that reported binding studies must be treated with caution unless endogenous fatty acids have been removed from the sample prior to analysis. | ||
