TAZ2 truncation confers overactivation of p300 and cellular vulnerability to HDAC inhibition
The histone acetyltransferase p300/CBP is composed of several conserved domains, among which, the TAZ2 domain is known as a protein-protein interaction domain that binds to E1A and various transcription factors.

TRPM3-Induced Gene Transcription Is under Epigenetic Control
Transient receptor potential M3 (TRPM3) cation channels regulate numerous biological functions, including gene transcription. Stimulation of TRPM3 channels with pregnenolone sulfate activates stimulus-responsive transcription factors, which bind to short

Preferential genome targeting of the CBP co-activator by Rel and Smad proteins in early Drosophila melanogaster embryos. [PDF]
CBP and the related p300 protein are widely used transcriptional co-activators in metazoans that interact with multiple transcription factors. Whether CBP/p300 occupies the genome equally with all factors or preferentially binds together with some ...

Dysregulated gene expression contributes to most prevalent features in human cancers. Here, we show that most subtypes of acute myeloid leukemia (AML) depend on the aberrant assembly of MYB transcriptional co-activator complex.

CBP/p300 HAT maintains the gene network critical for β cell identity and functional maturity
Loss of β cell identity and functional immaturity are thought to be involved in β cell failure in type 2 diabetes. CREB-binding protein (CBP) and its paralogue p300 act as multifunctional transcriptional co-activators and histone acetyltransferases (HAT)

Ku80 cooperates with CBP to promote COX-2 expression and tumor growth. [PDF]
Cyclooxygenase-2 (COX-2) plays an important role in lung cancer development and progression. Using streptavidin-agarose pulldown and proteomics assay, we identified and validated Ku80, a dimer of Ku participating in the repair of broken DNA double ...

Natural Products with Antitumor Potential Targeting the MYB-C/EBPβ-p300 Transcription Module
The transcription factor MYB is expressed predominantly in hematopoietic progenitor cells, where it plays an essential role in the development of most lineages of the hematopoietic system. In the myeloid lineage, MYB is known to cooperate with members of

The C/H3 domain of p300 is required to protect VRK1 and VRK2 from their downregulation induced by p53. [PDF]
BACKGROUND: The vaccinia-related kinase 1 (VRK1) protein, an activator of p53, can be proteolytically downregulated by an indirect mechanism, which requires p53-dependent transcription. PRINCIPAL FINDINGS: In this work we have biochemically characterized

Chromatin Targeting of HIPK2 Leads to Acetylation-Dependent Chromatin Decondensation
The protein kinase homeodomain-interacting protein kinase 2 (HIPK2) plays an important role in development and in the response to external cues. The kinase associates with an exceptionally large number of different transcription factors and chromatin ...
