Expressed in E. coli fused to an amino terminal hexahistidine tag.The peroxisome proliferator-activated receptor-g (PPAR-g) is a member of the nuclear receptor family of transcription factors, a large and diverse group of proteins that mediate ligand-dependent transcriptional activation and repression. Expression of PPAR-g is an early and pivotal event in the differentiation of adipocytes. PPAR-g influences the storage of fatty acids in the adipose tissue and plays a role in adipocyte differentiation. It also binds to DNA as a heterodimer with retinoid X receptor (RXR), activating expression of target genes after binding ligand.
