[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 ==
 +
The functional interaction between the orphan nuclear receptors small heterodimer partner (SHP) and liver receptor homolog 1 (LRH-1), where SHP binds to LRH-1 and represses its constitutive transcriptional activity, is crucial for regulating genes involved in cholesterol homeostasis. Here, we report structural and biochemical analyses of the LRH-1/SHP interaction. The crystal structure and modeling studies of the LRH-1 ligand-binding domain bound to either of the two LXXLL-related motifs of SHP show that the receptor undergoes conformational changes to accommodate the SHP docking and reveal key residues that determine the potency and selectivity of SHP binding. Through a combination of mutagenesis and binding studies, we demonstrate that only the second SHP LXXLL motif is required for repressing LRH-1, and this motif displays a strong preference for binding to LRH-1 over the closely related receptor steroidogeneic factor 1 (SF-1). Structural comparisons indicate that this binding selectivity is determined by residues flanking the core LXXLL motifs. These results establish a structural model for understanding how SHP interacts with LRH-1 to regulate cholesterol homeostasis and provide new insights into how nuclear receptor/coregulator selectivity is achieved.
