Histone h3k27 acetylation

WebbHistone H3 is one of the DNA-binding proteins found in the chromatin of all eukaryotic cells. H3 along with four core histone proteins binds to DNA forming the structure of the nucleosome. Histones play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. WebbH3K27 acetylation and trimethylation (H3K27ac and H3K27me3) mark distinct chromatin regions and have distinct functions. For instance, in yeast cells, H3K27ac, catalyzed by both Gcn5 and Rtt109 lysine acetyltransferases, is likely to occur on newly synthesized histone H3 ( Burgess et al. 2010 ).

Webb3 mars 2024 · H3K27 is a specific histone protein (H3) that is acetylated at lysine 27 (H3K27Ac), a marker of transcriptional activity. Thus, the inhibition of H3K27 acetylation may orchestrate the expression of IL-9 in kidney diseases. WebbHistone H3 is primarily acetylated at Lys9, 14, 18, 23, 27, and 56. Acetylation of H3 at Lys9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms (2,3). Phosphorylation at Ser10, Ser28, and Thr11 of histone H3 is tightly correlated with chromosome condensation during both mitosis and meiosis (8-10).
