CREB-binding protein
CREB-binding protein (CBP) is a transcription activator. CREB is cAMP response element-binding protein which is a cellular transcription factor which binds to DNA and regulates transcription. CBP acetylates histones. It binds to phosphorylated CREB and enhances its activity. CBP contains several domains. Among them the lysine recognition bromodomain; domains KIX, TAZ1 and TAZ2 which bind sequences spanning the transactivation domain of transcription factor p53; IBiD which binds the interferon response; ZZ is a zinc-binding motif; CH1 interacts with the N-terminal of p73.
