Disease

[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: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]

Function

[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.^[5] ^[6] ^[7] ^[8]

Publication Abstract from PubMed

Lysine acetylation of human tumor suppressor p53 in response to cellular stress signals is required for its function as a transcription factor that regulates cell cycle arrest, senescence, or apoptosis. Here, we report small molecules that block lysine 382-acetylated p53 association with the bromodomain of the coactivator CBP, an interaction essential for p53-induced transcription of the cell cycle inhibitor p21 in response to DNA damage. These chemicals were discovered in target structure-guided nuclear magnetic resonance spectroscopy screening of a focused chemical library constructed based on the structural knowledge of CBP bromodomain/p53-AcK382 binding. Structural characterization shows that these chemicals inhibit CBP/p53 association by binding to the acetyl-lysine binding site of the bromodomain. Cell-based functional assays demonstrate that the lead chemicals can modulate p53 stability and function in response to DNA damage.
