In contrast, when HSF2-beta is expressed at levels exceeding those of endogenous HSF2-alpha , the hemin-induced DNA binding activity and transcription of heat shock genes are repressed, whereas overexpression of HSF2-alpha results in an enhanced hemin response .
 ( protein: HSF2-beta, None) , ( protein: hemin, None) , ( protein: HSF2-alpha, None) , ( protein: endogenous HSF2-alpha, None) , ( protein: HSF2-alpha, None) , ( DNA: heat shock genes, None)
