製品の詳細

Cyclic AMP-responsive enhancer binding protein (CREB) binding protein (CBP) and p300 are closely related transcriptional coactivators that have been shown to directly interact with many different DNA-binding transcription factors including nuclear hormone receptors, CREB (cyclic AMP-responsive enhancer binding protein), c-Fos, c-Jun/v-Jun, c-Myb/v-Myb, TFIIB and MyoD.Both CBP and p300 have been shown to display histone acetyltransferase (HAT) activity, capable of acetylating all four core histone particles in nucleosomes.As a result of HAT activity, it has been suggested CBP and p300 may play a direct role in activating chromatin for transcription.Single point mutations in CBP have been proposed as causative factors in the developmental abnormalities of Rubinstein-Taybi syndrome (RTS).Although both CBP and p300 appear to function similarly, the inability of p300 to rescue CBP malfunction iRTS suggests intrinsic functional differences between CBP and p300.

補足情報

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.

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).
