Figure 4-26The overall structural organization of the core histones

(A) Each of the core histones contains an N-terminal tail, which is subject to several forms of covalent modification, and a histone fold region, as indicated. (B) The structure of the histone fold, which is formed by all four of the core histones. (C) Histones 2A and 2B form a dimer through an interaction known as the “handshake.” Histones H3 and H4 form a dimer through the same type of interaction, as illustrated in Figure 4-27.
