[[http://www.uniprot.org/uniprot/CBP_HUMAN CBP_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:[http://omim.org/entry/180849 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.<ref>PMID:11331617</ref> <ref>PMID:12114483</ref> <ref>PMID:12566391</ref> <ref>PMID:15706485</ref>

== Function ==
 +
[[http://www.uniprot.org/uniprot/CBP_HUMAN CBP_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.<ref>PMID:9707565</ref> <ref>PMID:11154691</ref> <ref>PMID:12738767</ref> <ref>PMID:12929931</ref>

== Publication Abstract from PubMed ==
 +
Overexpression of the CREB-binding protein (CBP), a bromodomain-containing transcription coactivator involved in a variety of cellular processes, has been observed in several types of cancer with a correlation to aggressiveness. We have screened a library of nearly 1500 fragments by high-throughput docking into the CBP bromodomain followed by binding energy evaluation using a force field with electrostatic solvation. Twenty of the 39 fragments selected by virtual screening are positive in one or more ligand-observed nuclear magnetic resonance (NMR) experiments. Four crystal structures of the CBP bromodomain in complex with in silico screening hits validate the pose predicted by docking. Thus, the success ratio of the high-throughput docking procedure is 50% or 10% if one considers the validation by ligand-observed NMR spectroscopy or X-ray crystallography, respectively. Compounds 1 and 3 show favorable ligand efficiency in two different in vitro binding assays. The structure of the CBP bromodomain in the complex with the brominated pyrrole 1 suggests fragment growing by Suzuki coupling.
