Webb22 maj 2013 · The crystal structure of the FACT histone chaperone domain Spt16M in complex with the H2A–H2B heterodimer is solved; Spt16M makes several interactions with histones and seems to block the ...
WebbThe canonical histone genes (H2A, H2B, H3, and H4) are encoded in the genome by a gene cluster that is expressed exclusively during S-phase, the phase of DNA replication, to allow newly expressed histones to be incorporated into the newly replicated DNA. Except for histone H4, noncanonical variants of all other core histones (H2A, H2B, and H3 ... WebbHistone H2B combines with Histone H2A to form the H2A-H2B heterodimer. Two H2A/H2B heterodimers interact with an H3/H4 tetramer to form the histone octamer. Histone H2B is also modified by various enzymes and can act as a substrate for them. These modifications have been shown to be important in gene regulation.
