[[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 ==

BET bromodomain inhibitors are widely used both as chemical tools to study the biological role of their targets in living organisms, and as candidates for drug development against several cancer variants and human disorders. However, non-BET bromodomains such as those in p300 and CBP are less studied. Here, we introduce XDM-CBP, a highly potent and selective inhibitor for the bromodomains of CBP and p300 derived from a pan-selective BET BRD-binding fragment. In addition to X-ray crystal structure analysis and thermodynamic profiling, we used XDM-CBP in in vitro cell screenings of several cancer cell lines to study its inhibitory potential on cancer cell proliferation. Our results demonstrate that XDM-CBP is a potent and selective CBP/p300 inhibitor that acts on specific cancer cell lines, in particular malignant melanoma, breast cancer, and leukemia.
