'''CREB-binding protein''' or '''CREBBP''' (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. <ref>PMID:8413673</ref>

Mutations in CBP cause Rubinstein-Taybi syndrome.<ref>PMID:7630403</ref>

== Structural highlights ==

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 (Cys- and His-rich region 1) interacts with the N-terminal of p73.
