Role of Histone H3K4 Methyltransferase in Regulating Monascus …

In biology, histones are highly basic proteins abundant in lysine and arginine residues that are found in eukaryotic cell nuclei. They act as spools around which DNA winds to create structural units called nucleosomes. Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. … Webb21 okt. 2010 · Biotinylations at histone H4 lysine 8 and lysine 12 have been associated with heterochromatin structures, gene silencing, mitotic condensation of chromatin, and …
