CREB-binding protein

Function 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. Disease Mutations in CBP cause Rubinstein-Taybi syndrome. 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. with chain A. Water molecules are shown as red spheres. with chain B (3p1c).
