Function

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.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Most triacylglycerol-lowering fibrates have been developed in the 1960s-1980s before their molecular target, peroxisome proliferator-activated receptor alpha (PPARalpha), was identified. Twenty-one ligand-bound PPARalpha structures have been deposited in the Protein Data Bank since 2001; however, binding modes of fibrates and physiological ligands remain unknown. Here we show thirty-four X-ray crystallographic structures of the PPARalpha ligand-binding domain, which are composed of a "Center" and four "Arm" regions, in complexes with five endogenous fatty acids, six fibrates in clinical use, and six synthetic PPARalpha agonists. High-resolution structural analyses, in combination with coactivator recruitment and thermostability assays, demonstrate that stearic and palmitic acids are presumably physiological ligands; coordination to Arm III is important for high PPARalpha potency/selectivity of pemafibrate and GW7647; and agonistic activities of four fibrates are enhanced by the partial agonist GW9662. These results renew our understanding of PPARalpha ligand recognition and contribute to the molecular design of next-generation PPAR-targeted drugs.
