== Function == | |||
[https://www.uniprot.org/uniprot/PPARA_HUMAN PPARA_HUMAN] Ligand-activated transcription factor. Key regulator of lipid metabolism. Activated by the endogenous ligand 1-palmitoyl-2-oleoyl-sn-glycerol-3-phosphocholine (16:0/18:1-GPC). Activated by oleylethanolamide, a naturally occurring lipid that regulates satiety (By similarity). Receptor for peroxisome proliferators such as hypolipidemic drugs and fatty acids. Regulates the peroxisomal beta-oxidation pathway of fatty acids. Functions as transcription activator for the ACOX1 and P450 genes. Transactivation activity requires heterodimerization with RXRA and is antagonized by NR2C2.<ref>PMID:7684926</ref> <ref>PMID:7629123</ref> <ref>PMID:9556573</ref> <ref>PMID:10195690</ref> | |||

== Publication Abstract from PubMed == | |||
17-Hydroxy docosahexaenoic acid (17-HDHA) is an oxidized form of docosahexaenoic acid (DHA) and known as a specialized proresolving mediator. We found that a further oxidized product, 17-oxodocosahexaenoic acid (17-oxoDHA), activates peroxisome proliferator-activated receptors gamma (PPARgamma) and PPARalpha in transcriptional assays and thus can be classified as an alpha/gamma dual agonist. ESI mass spectroscopy and X-ray crystallographic analysis showed that 17-oxoDHA binds to PPARgamma and PPARalpha covalently, making 17-oxoDHA the first of a novel class of PPAR agonists, the PPARalpha/gamma dual covalent agonist. Furthermore, the covalent binding sites were identified as Cys285 for PPARgamma and Cys275 for PPARalpha. | |||
