Isothiazolones as inhibitors of PCAF and p300 histone acetyltransferase activity.
Histone acetylation plays an important role in regulating the chromatin structure and is tightly regulated by two classes of enzyme, histone acetyltransferases (HAT) and histone deacetylases (HDAC). Deregulated HAT and HDAC activity plays a role in the development of a range of cancers. Consequently, inhibitors of these enzymes have potential as anticancer agents. Several HDAC inhibitors have b...
متن کاملPhysical association between the histone acetyl transferase CBP and a histone methyl transferase.
CBP (CREB-binding protein) is involved in transcriptional activation by a great variety of sequence-specific transcription factors. CBP has been shown to activate transcription through its histone acetyl transferase activity. Acetylation is a common post-translational modification of nucleosomal histone N-terminal tails, which generally correlates with transcriptional activation. Histone N-term...
متن کاملInhibition of histone acetyltransferase function of p300 by PKCy
Protein kinase Cy (PKCy) is one of the functionally distinct isoforms in PKC family. p300 is a histone acetyltransferase/transcription coactivator. They share certain properties, such as ubiquitous expression, growth and tumor suppression, and ability to enhance differentiation and apoptosis. In this study, we found that PKCy but not classical PKC, specifically phosphorylates p300 at serine 89 ...
متن کاملInhibition of p300 histone acetyltransferase by viral interferon regulatory factor.
Kaposi's sarcoma-associated herpesvirus (KSHV) has been consistently identified in Kaposi's sarcomas, body cavity-based lymphomas, and some forms of Castleman's disease. The K9 open reading frame of KSHV encodes a viral interferon regulatory factor (vIRF) which functions as a repressor for cellular interferon-mediated signal transduction and as an oncogene to induce cell growth transformation. ...
متن کاملA rapid and sensitive assay for histone acetyl-transferase activity.
Histone acetyl-transferases (HATs) seem to be key elements in the regulation of transcription. We have designed an enzymatic assay to quantify HAT enzymatic activity. In this assay, the substrate is a peptide corresponding to the 24 first amino acids of histone H4 which is coupled to biotin. After acetylation using [14C]acetyl-CoA, the peptide is purified on streptavidin beads and the associate...
