Tsa acetylation

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 … WebSpecificity / Sensitivity. Acetylated-Lysine Mouse mAb (Ac-K-103) detects proteins only when posttranslationally modified by acetylation on the epsilon-amine groups of lysine residues. Detection of acetylated lysine by this antibody is largely independent of surrounding amino acid sequence. The antibody has been shown to recognize acetylated ...

WebInstead, TSA increased the acetylation of histones associated with the NATb promoter. This allowed recruitment of Sp1 to the promoter along with acetylated histones. We propose that NAT1 transcription is partially repressed by the local chromatin condensation in the vicinity of NATb and that histone deacetylase inhibition leads to up-regulation of NAT1 …
