(Submitter supplied) Genome-wide distribution of histone H3K18 and H3K27 acetyltransferases, Crebbp (CBP) and Ep300 (p300), is used to map enhancers and promoters, but whether these elements functionally require CBP/p300 remains largely uncertain. We investigated this relationship by comparing genomic CBP recruitment with gene expression in wild type and CBP/p300 double-knockout fibroblasts. ChIP-seq revealed nearby CBP recruitment for 20 percent of constitutively expressed genes, but surprisingly, three-quarters of these were unaffected or slightly activated by CBP/p300 deletion. more...

(Submitter supplied) The metazoan-specific acetyltransferase p300/CBP is involved in activating signalinduced, enhancer-mediated transcription of cell-type-specific genes. However, the global kinetics and mechanisms of p300/CBP activity-dependent transcription activation remain poorly understood. We performed genome-wide, time-resolved analyses to show that enhancers and super-enhancers are dynamically activated through p300/CBP-catalyzed acetylation, deactivated by the opposing deacetylase activity, and kinetic acetylation directly contributes to maintaining cell identity at very rapid timescales. more...

(Submitter supplied) C4-2B prostate cancer cells were transfected with siRNA against a non-specific (NS) sequence, siRNA specifically targeting EP300, or siRNA specifically targeting CREBBP. We tested the hypothesis that their exists different subgroups of genes that are preferentially affected by p300 or CBP depletion.

(Submitter supplied) 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 bound by P300 and CBP.

(Submitter supplied) Histone H3K4me1/2 methyltransferases MLL3/MLL4 and H3K27 acetyltransferases CBP/p300 are major enhancer epigenomic writers. To understand how these epigenomic writers orchestrate enhancer landscapes during cell differentiation, we have profiled genomic binding of MLL4, CBP, lineage-determining transcription factors, as well as transcriptome and epigenome during adipogenesis of immortalized preadipocytes derived from mouse brown adipose tissue (BAT). more...

(Submitter supplied) We investigated the impact in transcription, chromatin acetylation and behavior of eliminating either CBP or p300 in excitatory neurons of the adult forebrain. The elimination of CBP reduced the expression of plasticity genes. The importance of CBP became more prominent in paradigms that involved a chronic or recurrent change in transcription, including kindling and neuroadaptation to environmental enrichment, in which CBP loss interfered with the establishment of activity-induced transcriptional and epigenetic adaptive changes in response to stimulus or experience. more...
