Cotransfection of expression plasmids encoding the protein kinase A inhibitor , or an inactive protein kinase A ( PKA ) catalytic beta subunit , inhibited both forskolin and PACAP activation of chromogranin A transcription , revealing that PACAP - induced trans - activation is highly dependent on PKA .
