| + | [[http://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:[http://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:[http://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:[http://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. | ||

| + | [[http://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> | ||

| + | Site-specific labeling is an important methodology to elucidate the biological function of a target protein. Here, we report a strategy for site-specific chemical labeling, termed the "on-site reaction". We designed and readily synthesized a bifunctional ligand possessing two reaction sites, an enone and an azide moiety. This strategy involves an on-site conjugate addition reaction with protein followed by a Huisgen cycloaddition reaction. We demonstrate this strategy by using fluorescein as a probe and peroxisome proliferator activated receptor gamma (PPARgamma) as a target protein. The reactions were evaluated by ESI-mass analysis and the binding site and modes of binding were revealed by X-ray crystallization analysis. The proposed methodology can easily convert a covalent ligand into chemical tool for protein functional analysis and the identification of drug targets. | ||
