WebHistone-deacetylase inhibitors (HDCACi) represent a new class of antitumor agents currently in clinical development. They target a family of enzymes which catalyse histone acetylation modifications, in particular for histones H2A, H2B, H3 and H4. These proteins stabilize the nucleosome core, fundamental unity of chromatin which represents the first level of DNA … WebPreparation Note. Trichostatin A is soluble in methanol at 1.90 - 2.10 mg/ml and yields a clear, colorless to faint yellow/tan solution. It is also soluble in DMSO, DMF, acetonitrile, ethanol and lower alcohols. Trichostatin A is sparingly soluble in chloroform, ethyl acetate, acetone, and benzene. However, it is insoluble in water.

WebPost-translational modifications such as phosphorylation, acetylation, glycosylation, and proteolytic processing significantly affect the activity of this protein, which can be an activator or a repressor. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2014]. WebHere we show that TSA strongly induces HIV-1 transcription on chromatin in vitro, concomitant with an enhancer factor-assisted increase in the level of acetylated histone H4. TSA treatment, however, did not detectably alter enhancer factor binding or the positioning of nuc-1 on the majority of the chromatin templates indicating that protein ...
