== Disease ==
[https://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:[https://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 ==
[https://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 ==
Many different zinc binding modules have been identified. Their abundance and variety suggests that the formation of zinc binding folds might be relatively common. We have determined the structure of CH1(1), a 27-residue peptide derived from the first cysteine/histidine-rich region (CH1) of CREB binding protein (CBP). This peptide forms a highly ordered zinc-dependent fold that is distinct from known folds. The structure differs from a subsequently determined structure of a larger region from the CH3 region of CBP, and the CH1(1) fold probably represents a nonphysiologically active form. Despite this, the fold is thermostable and tolerant to both multiple alanine mutations and changes in the zinc-ligand spacing. Our data support the idea that zinc binding domains may arise frequently. Additionally, such structures may prove useful as scaffolds for protein design, given their stability and robustness.

A new zinc binding fold underlines the versatility of zinc binding modules in protein evolution.,Sharpe BK, Matthews JM, Kwan AH, Newton A, Gell DA, Crossley M, Mackay JP Structure. 2002 May;10(5):639-48. PMID:12015147<ref>PMID:12015147</ref>
