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 {ECO:0000250}. Chromosome {ECO:0000250}.
CC -!- PTM: Phosphorylated at Ser-11. This is required for transcriptional
CC activation through TBP recruitment to the promoters. Phosphorylation at
CC Ser-11 also promotes subsequent acetylation at Lys-15 (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Mono-, di- and trimethylation of Lys-5 by the COMPASS complex
CC activates gene expression by regulating transcription elongation and
CC plays a role in telomere length maintenance. Lys-5 methylation
CC enrichment correlates with transcription levels, and occurs in a 5' to
CC 3' gradient with tri-methyl enrichment at the 5'-end of genes, shifting
CC to di-methyl and then mono-methyl. The COMPASS mediated di and
CC trimethylation of Lys-5 requires histone H2B monoubiquitination.
CC Methylation of Lys-37 by SET2 represses gene expression. Methylation of
CC Lys-80 by DOT1 is required for association of SIR proteins with
CC telomeric regions and for telomeric silencing (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Acetylation of histone H3 leads to transcriptional activation.
CC Acetylation at Lys-15 is promoted by the phosphorylation at Ser-11.
CC Acetylation at Lys-57 occurs predominantly in newly synthesized H3
CC molecule during G1, S and G2/M of the cell cycle and may be involved in
CC DNA repair (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the histone H3 family. {ECO:0000305}.
