DiseaseCBP_HUMAN Note=Chromosomal aberrations involving CREBBP may be a cause of acute myeloid leukemias. Translocation t(8;16)(p11;p13) with KAT6A; translocation t(11;16)(q23;p13.3) with MLL/HRX; translocation t(10;16)(q22;p13) with KAT6B. KAT6A-CREBBP may induce leukemia by inhibiting RUNX1-mediated transcription. Defects in CREBBP are a cause of Rubinstein-Taybi syndrome type 1 (RSTS1) [MIM:180849. RSTS1 is an autosomal dominant disorder characterized by craniofacial abnormalities, broad thumbs, broad big toes, mental retardation and a propensity for development of malignancies.[1] [2] [3] [4] FunctionCBP_HUMAN Acetylates histones, giving a specific tag for transcriptional activation. Also acetylates non-histone proteins, like NCOA3 and FOXO1. Binds specifically to phosphorylated CREB and enhances its transcriptional activity toward cAMP-responsive genes. Acts as a coactivator of ALX1 in the presence of EP300.[5] [6] [7] [8] Publication Abstract from PubMedWe analyze 20 crystal structures of complexes between the CBP bromodomain and small-molecule ligands that belong to eight different chemotypes identified by docking. The binding motif of the moiety that mimics the natural ligand (acetylated side chain of lysine) at the bottom of the binding pocket is conserved. In stark contrast, the rest of the ligands form different interactions with different side chains and backbone polar groups on the outer rim of the binding pocket. Hydrogen bonds are direct or water-bridged. van der Waals contacts are optimized by rotations of hydrophobic side chains and a slight inward displacement of the ZA loop. Rare types of interactions are observed for some of the ligands.
