Dynamic atlas of histone modi

Webhistone modi cations are indicated by names like H4K5ac (acetylation modi cation on the 5th amino acid lysine (K) of the H4 protein), H3K27me3 (tri-methylation marks on the 27th amino acid lysine (K) of the H3 protein) etc [8, 9]. Presence of each of these modi cations encode some speci c information relevant for gene regulation. Even though the WebThe nucleosome, made up of four core histone proteins (H2A, H2B, H3, and H4), and linker histone H1 are the primary building blocks of chromatin. Originally thought to function as a static scaffold for DNA packaging, histones have more recently been shown to be dynamic proteins, undergoing multiple types of post-translational modifications that ...
