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 -!- FUNCTION: Has broad antibacterial activity. May contribute to the
CC formation of the functional antimicrobial barrier of the colonic
CC epithelium, and to the bactericidal activity of amniotic fluid (By
CC similarity). {ECO:0000250}.
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 at Lys-35 (H2BK34Ub) by the MSL1/MSL2 dimer is
CC required for histone H3 'Lys-4' (H3K4me) and 'Lys-79' (H3K79me)
CC methylation and transcription activation at specific gene loci, such as
CC HOXA9 and MEIS1 loci. Similarly, monoubiquitination at Lys-121
CC (H2BK120Ub) by the RNF20/40 complex gives a specific tag for epigenetic
CC transcriptional activation and is also prerequisite for histone H3
CC 'Lys-4' and 'Lys-79' methylation. It also functions cooperatively with
CC the FACT dimer to stimulate elongation by RNA polymerase II. H2BK120Ub
CC also acts as a regulator of mRNA splicing: deubiquitination by USP49 is
CC required for efficient cotranscriptional splicing of a large set of
CC exons (By similarity). {ECO:0000250|UniProtKB:P33778}.
CC -!- PTM: Phosphorylated on Ser-15 (H2BS14ph) by STK4/MST1 during apoptosis;
CC which facilitates apoptotic chromatin condensation. Also phosphorylated
CC on Ser-15 in response to DNA double strand breaks (DSBs), and in
CC correlation with somatic hypermutation and immunoglobulin class-switch
CC recombination. Phosphorylation at Ser-37 (H2BS36ph) by AMPK in response
CC to stress promotes transcription (By similarity).
CC {ECO:0000250|UniProtKB:P33778, ECO:0000250|UniProtKB:Q64475}.
CC -!- PTM: Crotonylation (Kcr) is specifically present in male germ cells and
CC marks testis-specific genes in post-meiotic cells, including X-linked
CC genes that escape sex chromosome inactivation in haploid cells.
CC Crotonylation marks active promoters and enhancers and confers
CC resistance to transcriptional repressors. It is also associated with
CC post-meiotically activated genes on autosomes (By similarity).
CC {ECO:0000250|UniProtKB:P33778}.
CC -!- PTM: GlcNAcylation at Ser-113 promotes monoubiquitination of Lys-121.
CC It fluctuates in response to extracellular glucose, and associates with
CC transcribed genes (By similarity). {ECO:0000250|UniProtKB:P62807}.
CC -!- PTM: Lactylated in macrophages by EP300/P300 by using lactoyl-CoA
CC directly derived from endogenous or exogenous lactate, leading to
CC stimulates gene transcription. {ECO:0000250|UniProtKB:P33778}.
CC -!- SIMILARITY: Belongs to the histone H2B family. {ECO:0000305}.
