ProteomicsTime-resolved analysis reveals rapid dynamics and broad scope of the CBP/p300 acetylome
The acetyltransferases CBP and p300 are multifunctional transcriptional co-activators; however, their acetylation targets, site-specific acetylation kinetics, and function in proteome regulation are incompletely understood. We combined quantitative proteomics with novel CBP/p300-specific catalytic i...

ProteomicsTargeted degradation of the enhancer lysine acetyltransferases CBP and p300
The enhancer factors CBP/p300 maintain gene expression programs through lysine acetylation of chromatin and transcriptional regulators and by scaffolding functions mediated by several protein-protein interaction domains. We have designed dCBP-1, a compound that induces degradation of CBP/p300, and ...

GenomicsGenome-wide assessment of differential roles for p300 and CBP in transcription regulation
Through ChIP-Seq analysis with the Illumina Whole Genome Analyzer, we identify binding sites for P300 (EP300) and CBP (CREBBP) in Human glioblastoma T98G cells that were cell cycle synchronized before and after stimulation. In our analysis, we focused on the identification of genes differentially bo...

TranscriptomicsDevelopment of gene expression signatures for knockdown of synthetic lethal gene
We performed genome-wide expression profiling analysis to define the genes underlying the synthetic-lethal relationship between CBP and p300. We extracted 1,936 genes whose expression levels changed >2-fold upon p300-knockdown (KD) in CBP-KO cells, or upon CBP-KD in p300-KO cells, but not in either ...

TranscriptomicsGene regulation by CBP-p300 in the lens placode - E9.5
Wild type or CBP/p300 fx/fx; Le-Cre-positive (CBP/p300-/-) surface ectoderm from E9.5 mouse embryos was laser micodissected from three embryos of each genotype. Total RNA was purified, pooled for each genotype and triplicate samples were reverse transcribed and amplified using a NuGEN kit. cDNA was ...

TranscriptomicsTwo Histone/Protein Acetyltransferases, CBP and p300, Are Indispensable for Foxp3+ T-regulatory Cell Development and Function
T-regulatory (Treg) cells are important to immune homeostasis, and Treg cell deficiency or dysfunction leads to autoimmune disease. An histone/protein acetyltransferase (HAT), p300, was recently found important for Treg function and stability, but further insights into the mechanisms by which p300 o...

ProteomicsDefinition of aberrant MYB CBP/P300 complex in AML
Dysregulated gene expression is one of the most prevalent features in human cancers. Here, we show that most subtypes of acute myeloid leukemia (AML) depend on the aberrant assembly of the MYB transcriptional co-activator complex. By rapid and selective peptidomimetic interference with the binding o...

GenomicsDUX4 recruits p300/CBP through its C-terminus and induces global H3K27 acetylation changes
Ectopic expression of the double homeodomain transcription factor DUX4 causes facioscapulohumeral muscular dystrophy (FSHD). Mechanisms of action of DUX4 are currently unknown. Using immortalized human myoblasts with a titratable DUX4 transgene, we identify by mass spectrometry an interaction betwee...

TranscriptomicsRole of RelA:CBP/p300 interaction on RelA-activated genes
A structure-function study of NF-kB subunit RelA and coactivator CBP/p300 interaction reveals the critical role of CBP/p300 in recruitment of RelA to its target promoter site. mRNA profiles of unstimulated or stimulated with TNFa rela-/- MEF reconstituted with RelA wild type or mutants were generate...
