Characterization of a bipartite activator domain in transcription factor CREB.


In this paper, we characterize a trans-activating region in CREB, termed alpha, that interacts cooperatively with the kinase A phosphorylation motif to stimulate transcription. The alpha region appears to be encoded by an alternate exon that is deleted in a CREB-related cDNA named delta CREB. Both proteins are expressed in eukaryotic cells, although the… (More)
