PPARγ gene organization (A) and a simplified representation of action of PPAR:RXR heterodimer and ligands in transcriptional process (B). Under the presence of ligands, corepressor is released from PPAR:RXR heterodimer, enabling it to bind to to cofactor HAT complex. With further recruitment of general transcription complexes, transcription process can resume. AF-1; activation function-1. DBD; DNA binding domain. LBD; ligand binding domain. D; hinge domain linking DBD and LBD. PPRE; peroxisome proliferator activated receptor responseive element. HAT; histone acetyltransferase.
