We demonstrate that JunD , a component of the AP-1 transcription factor complex , activates transcription of the human proenkephalin gene in a fashion that is completely dependent upon the cAMP-dependent protein kinase , protein kinase A .
 protein: protein kinase A; protein: JunD; DNA: human proenkephalin gene; protein: AP-1 transcription factor complex; protein: cAMP-dependent protein kinase
