[https://www.uniprot.org/uniprot/PPARG_HUMAN PPARG_HUMAN] Note=Defects in PPARG can lead to type 2 insulin-resistant diabetes and hyptertension. PPARG mutations may be associated with colon cancer.  Defects in PPARG may be associated with susceptibility to obesity (OBESITY) [MIM:[https://omim.org/entry/601665 601665]. It is a condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat.<ref>PMID:9753710</ref>   Defects in PPARG are the cause of familial partial lipodystrophy type 3 (FPLD3) [MIM:[https://omim.org/entry/604367 604367]. Familial partial lipodystrophies (FPLD) are a heterogeneous group of genetic disorders characterized by marked loss of subcutaneous (sc) fat from the extremities. Affected individuals show an increased preponderance of insulin resistance, diabetes mellitus and dyslipidemia.<ref>PMID:12453919</ref> <ref>PMID:11788685</ref>   Genetic variations in PPARG can be associated with susceptibility to glioma type 1 (GLM1) [MIM:[https://omim.org/entry/137800 137800]. Gliomas are central nervous system neoplasms derived from glial cells and comprise astrocytomas, glioblastoma multiforme, oligodendrogliomas, and ependymomas. Note=Polymorphic PPARG alleles have been found to be significantly over-represented among a cohort of American patients with sporadic glioblastoma multiforme suggesting a possible contribution to disease susceptibility.
== Function ==
[https://www.uniprot.org/uniprot/PPARG_HUMAN PPARG_HUMAN] Receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Once activated by a ligand, the receptor binds to a promoter element in the gene for acyl-CoA oxidase and activates its transcription. It therefore controls the peroxisomal beta-oxidation pathway of fatty acids. Key regulator of adipocyte differentiation and glucose homeostasis. Acts as a critical regulator of gut homeostasis by suppressing NF-kappa-B-mediated proinflammatory responses.<ref>PMID:9065481</ref> <ref>PMID:16150867</ref> <ref>PMID:20829347</ref>

== Publication Abstract from PubMed ==
Peroxisome proliferator-activated receptors (PPARs) belong to the nuclear hormone receptor family, which is defined as transcriptional factors that are activated by the binding of ligands to their ligand-binding domains (LBDs). Although the three PPAR subtypes display different tissue distribution patterns and distinct pharmacological profiles, they all are essentially related to fatty-acid and glucose metabolism. Since the PPARs share similar three-dimensional structures within the LBDs, synthetic ligands which simultaneously activate two or all of the PPARs could be potent candidates in terms of drugs for the treatment of abnormal metabolic homeostasis. The structures of several PPAR LBDs were determined in complex with synthetic ligands, derivatives of 3-(4-alkoxyphenyl)propanoic acid, which exhibit unique agonistic activities. The PPARalpha and PPARgamma LBDs were complexed with the same pan agonist, TIPP-703, which activates all three PPARs and their crystal structures were determined. The two LBD-ligand complex structures revealed how the pan agonist is adapted to the similar, but significantly different, ligand-binding pockets of the PPARs. The structures of the PPARdelta LBD in complex with an alpha/delta-selective ligand, TIPP-401, and with a related delta-specific ligand, TIPP-204, were also determined. The comparison between the two PPARdelta complexes revealed how each ligand exhibits either a ;dual selective' or ;single specific' binding mode.
