IHC image of CREBBP staining in human pancreas formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab2832, 5μg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Supplementary information

CREBBP also known as CREB Binding Protein or CBP is a multifunctional protein with a molecular weight of approximately 265 kDa. This protein serves as a transcriptional coactivator and possesses intrinsic histone acetyltransferase (HAT) activity. CREBBP is ubiquitously expressed making it present in various tissues throughout the body. Its interaction with different transcription factors facilitates transcriptional activation by remodeling chromatin structure.
Biological function summary

CREBBP plays a pivotal role in regulating gene expression by serving as a coactivator that bridges transcription factors with the basal transcription machinery. CREBBP as part of large multiprotein complexes acetylates histones as well as non-histone proteins influencing chromatin accessibility and transcriptional efficiency. Its HAT activity contributes to the regulation of cell cycle differentiation and DNA repair.

Pathways

CREBBP integrates into both the p53 and Hedgehog signaling pathways modulating various cellular responses. In the p53 pathway CREBBP interacts with the tumor suppressor protein p53 enhancing p53’s ability to initiate expression of genes involved in cell cycle arrest and apoptosis. In the Hedgehog pathway CREBBP regulates transcription factors such as Gli proteins. The interplay between CREBBP and these pathways underlines its importance in maintaining cellular homeostasis and preventing oncogenesis.

Mutations or dysregulation of CREBBP are associated with Rubinstein-Taybi syndrome and various cancers including acute myeloid leukemia. In Rubinstein-Taybi syndrome CREBBP mutations impair cognitive development and skeletal malformations. In cancer particularly acute myeloid leukemia alterations in CREBBP disrupt normal cell growth regulation and lead to tumorigenesis. The protein's interaction with factors like p300 another histone acetyltransferase further emphasizes its critical involvement in these pathological conditions.

Target data

Acetylates histones, giving a specific tag for transcriptional activation (PubMed : 21131905, PubMed : 24616510). Mediates acetylation of histone H3 at 'Lys-18' and 'Lys-27' (H3K18ac and H3K27ac, respectively) (PubMed : 21131905). Also acetylates non-histone proteins, like DDX21, FBL, IRF2, MAFG, NCOA3, POLR1E/PAF53 and FOXO1 (PubMed : 10490106, PubMed : 11154691, PubMed : 12738767, PubMed : 12929931, PubMed : 24207024, PubMed : 28790157, PubMed : 30540930, PubMed : 35675826, PubMed : 9707565). Binds specifically to phosphorylated CREB and enhances its transcriptional activity toward cAMP-responsive genes. Acts as a coactivator of ALX1. Acts as a circadian transcriptional coactivator which enhances the activity of the circadian transcriptional activators : NPAS2-BMAL1 and CLOCK-BMAL1 heterodimers (PubMed : 14645221). Acetylates PCNA; acetylation promotes removal of chromatin-bound PCNA and its degradation during nucleotide excision repair (NER) (PubMed : 24939902). Acetylates POLR1E/PAF53, leading to decreased association of RNA polymerase I with the rDNA promoter region and coding region (PubMed : 24207024). Acetylates DDX21, thereby inhibiting DDX21 helicase activity (PubMed : 28790157). Acetylates FBL, preventing methylation of 'Gln-105' of histone H2A (H2AQ104me) (PubMed : 30540930). In addition to protein acetyltransferase, can use different acyl-CoA substrates, such as lactoyl-CoA, and is able to mediate protein lactylation (PubMed : 38128537). Catalyzes lactylation of MRE11 in response to DNA damage, thereby promoting DNA double-strand breaks (DSBs) via homologous recombination (HR) (PubMed : 38128537). Functions as a transcriptional coactivator for SMAD4 in the TGF-beta signaling pathway (PubMed : 25514493).
