[[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 == | |||
Bromodomain-containing proteins are key epigenetic regulators of gene transcription and readers of the histone code. However, the therapeutic benefits of modulating this target class are largely unexplored due to the lack of suitable chemical probes. This article describes the generation of lead molecules for the BET bromodomains through screening a fragment set chosen using structural insights and computational approaches. Analysis of 40 BRD2/fragment X-ray complexes highlights both shared and disparate interaction features, which that may be exploited for affinity and selectivity. Six representative crystal structures are then exemplified in detail. Two of the fragments are completely new bromodomain chemotypes, and three have never before been crystallized in a bromodomain, so our results significantly extend the limited public knowledge-base of crystallographic small molecule/bromodomain interactions. Certain fragments (including paracetamol) bind in a consistent mode to different bromodomains such as CREBBP, suggesting their potential to act as generic bromodomain templates. An important implication is that the bromodomains are not only a phylogenetic family, but also a system in which chemical and structural knowledge of one bromodomain gives insights transferrable to others. | |||
