Histone lysine
Histone acetylation and deacetylation are the processes by which the lysine residues within the N-terminal tail protruding from the histone core of the nucleosome are acetylated and deacetylated as part of gene regulation. Histone acetylation and deacetylation are essential parts of gene regulation. These reactions are typically catalysed by enzymes with "histone acetyltransfer… WebMar 24, 2024 · Lysine l-lactylation [K (l-la)] is a newly discovered histone mark that can be stimulated under conditions of high glycolysis, such as the Warburg effect. K (l-la) is associated with functions that are different from the widely studied histone acetylation.

In fact, we demonstrated that transducing cells with different H3.3 K–M mutants could interfere with associated methylation and, in turn, promote ...
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 … See more Five major families of histones exist: H1/H5, H2A, H2B, H3, and H4.
