Several distinct roles for hsp90 in modulating dioxin receptor function are therefore likely: correct folding of the ligand-binding domain, interference with Arnt heterodimerization, and folding of a DNA-binding conformation of the bHLH domain .
 ( protein: hsp90, None) , ( protein: bHLH domain, None) , ( protein: dioxin receptor, None) , ( protein: Arnt, None)
