CC -!- FUNCTION: Core component of nucleosome. Nucleosomes wrap and compact
CC DNA into chromatin, limiting DNA accessibility to the cellular
CC machineries which require DNA as a template. Histones thereby play a
CC central role in transcription regulation, DNA repair, DNA replication
CC and chromosomal stability. DNA accessibility is regulated via a complex
CC set of post-translational modifications of histones, also called
CC histone code, and nucleosome remodeling.
CC {ECO:0000256|ARBA:ARBA00002001}.
CC -!- SUBUNIT: The nucleosome is a histone octamer containing two molecules
CC each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and
CC two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of
CC DNA. {ECO:0000256|ARBA:ARBA00011538, ECO:0000256|RuleBase:RU000451}.
CC -!- SUBCELLULAR LOCATION: Chromosome {ECO:0000256|ARBA:ARBA00004286}.
CC Nucleus {ECO:0000256|ARBA:ARBA00004123, ECO:0000256|RuleBase:RU000451}.
CC -!- SIMILARITY: Belongs to the histone H2B family.
CC {ECO:0000256|ARBA:ARBA00006846, ECO:0000256|RuleBase:RU000451}.
