Function

Nuclear receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Once activated by a ligand, the nuclear receptor binds to DNA specific PPAR response elements (PPRE) and modulates the transcription of its target genes, such as acyl-CoA oxidase. It therefore controls the peroxisomal beta-oxidation pathway of fatty acids. Key regulator of adipocyte differentiation and glucose homeostasis. ARF6 acts as a key regulator of the tissue-specific adipocyte P2 (aP2) enhancer. Acts as a critical regulator of gut homeostasis by suppressing NF-kappa-B-mediated proinflammatory responses. {ECO:0000269PubMed:16150867, ECO:0000269PubMed:20829347, ECO:0000269PubMed:23525231, ECO:0000269PubMed:9065481}.

Subcellular Localization

Nucleus. Cytoplasm. Note=Redistributed from the nucleus to the cytosol through a MAP2K1/MEK1-dependent manner. CCRN4L/NOC enhances its nuclear translocation.

Disease Associations

Note=Defects in PPARG can lead to type 2 insulin- resistant diabetes and hyptertension. PPARG mutations may be associated with colon cancer.Obesity (OBESITY) [MIM:601665]: 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. {ECO:0000269PubMed:9753710}. Note=Disease susceptibility may be associated with variations affecting the gene represented in this entry.Lipodystrophy, familial partial, 3 (FPLD3) [MIM:604367]: A form of lipodystrophy characterized by marked loss of subcutaneous fat from the extremities. Facial adipose tissue may be increased, decreased or normal. Affected individuals show an increased preponderance of insulin resistance, diabetes mellitus and dyslipidemia. {ECO:0000269PubMed:11788685, ECO:0000269PubMed:12453919}. Note=The disease is caused by mutations affecting the gene represented in this entry.Glioma 1 (GLM1) [MIM:137800]: Gliomas are benign or malignant central nervous system neoplasms derived from glial cells. They comprise astrocytomas and glioblastoma multiforme that are derived from astrocytes, oligodendrogliomas derived from oligodendrocytes and ependymomas derived from ependymocytes. Note=Disease susceptibility may be associated with variations affecting the gene represented in this entry. 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.

Tissue Specificity

Highest expression in adipose tissue. Lower in skeletal muscle, spleen, heart and liver. Also detectable in placenta, lung and ovary. {ECO:0000269PubMed:9065481}.
