Accordingly, in transfection assays, expression vectors for the mutated HNF4 proteins activated transcription more efficiently than that for the wild-type protein-when cotransfected with the PKA catalytic subunit expression vector. Therefore, HNF4 is a direct target of PKA which might be involved in the transcriptional inhibition of liver genes by cAMP inducers.from full text (mutated HNF4 proteins at positions 133 and 134 Serine." . .
