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 -!- 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.
CC -!- SUBCELLULAR LOCATION: Nucleus. Chromosome.
CC -!- PTM: Monoubiquitination of Lys-118 gives a specific tag for epigenetic
CC transcriptional activation and is also prerequisite for histone H3
CC 'Lys-4' and 'Lys-79' methylation. {ECO:0000250}.
CC -!- PTM: GlcNAcylation at Ser-110 promotes monoubiquitination of Lys-118.
CC It fluctuates in response to extracellular glucose, and associates with
CC transcribed genes (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the histone H2B family. {ECO:0000305}.
