Pero, Xenopus/Amphibian,isome proliferator activated receptor delta (PPAR- delta,PorcinePAR-beta, Nuclear hormone recptor 1, NUCI1) binds pero, Xenopus/Amphibian,isome proliferators such as hypolipidemic drugs and fatty acids. Once activated by a ligand, the receptor binds to a promotor element in the gene for acyl-CoA o, Xenopus/Amphibian,idase and activates its transcription. PPAR- delta controls the pero, Xenopus/Amphibian,isomal beta-o, Xenopus/Amphibian,idation pathway of fatty acids, belongs to the nuclear hormone receptor NR1 subfamily, and contains 1 nuclear receptor DNA-binding domain.
