Histone location
WebbIt has long been known that histones, particularly H3 and H4, are methylated at a number of lysine (Lys) and arginine (Arg) residues. The major sites of Lys-methylation on histones identified so far are: Lys4, Lys9, Lys27, Lys36, Lys79 on H3 (see Fig. 1) … Webb15 juni 2024 · In wild type T. brucei H4K4 is acetylated in 80% of the histones and in cells lacking the histone acetyltransferase 3 (ΔHAT3 cells) H4K4ac levels drop to 5–10% with no growth defect (41, 42). Based on the analysis of deep sequencing data of gDNA, we estimated the number of histone H4 genes to be ∼43 (21.5 per homologous …
