    regulating basal, dopamine-induced and cAMP/PKA-dependent transcription in rat striatal neurons The activity The D1 receptor (D1R) is a Gαs/olf-coupled GPCR which activates a cAMP/PKA/DARPP-32 signalling cascade It is known that when Brd4 is activated by phosphorylation, it binds more readily to acetylated histones at promoters and enhancers; moreover, in non-neuronal cells, PKA signalling has been shown to increase We further found that cAMP/PKA signalling promotes Brd4 recruitment to dopamine-induced genes in striatal
