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. {ECO:0000305}.
CC -!- PATHWAY: Alkaloid biosynthesis. {ECO:0000303|PubMed:29229969}.
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:0000250|UniProtKB:P59169}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P59169,
CC ECO:0000255|PROSITE-ProRule:PRU00768}. Chromosome
CC {ECO:0000250|UniProtKB:P59169}. Nucleus, nucleolus
CC {ECO:0000250|UniProtKB:P59169}. Note=Localized at rDNA loci in the
CC nucleolus. {ECO:0000250|UniProtKB:P59169}.
CC -!- TISSUE SPECIFICITY: Expressed ubiquitously.
CC {ECO:0000269|PubMed:29229969}.
CC -!- PTM: Acetylation is generally linked to gene activation. Can be
CC acetylated to form H3K9ac, H3K14ac, H3K18ac and H3K23ac. H3K9ac could
CC compete with H3K9me and prevent gene silencing. H3K9ac is restricted to
CC euchromatin (By similarity). {ECO:0000250|UniProtKB:P59169}.
CC -!- PTM: Methylated to form mainly H3K4me, H3K9me, H3K18me, H3K23me,
CC H3K27me and H3K36me. H3K4me1/2/3, H3K9me3, H3K27me3 and H3K36me1/2/3
CC are typical marks for euchromatin, whereas heterochromatic
CC chromocenters are enriched in H3K9me1/2 and H3K27me1/2. H2BK143ub1 is
CC probably prerequisite for H3K4me (By similarity).
CC {ECO:0000250|UniProtKB:P59169}.
CC -!- PTM: Can be phosphorylated to form H3S10ph, H3T11ph and H3S28ph.
CC {ECO:0000250|UniProtKB:P59169}.
CC -!- SIMILARITY: Belongs to the histone H3 family. {ECO:0000305}.
CC -!- CAUTION: To ensure consistency between histone entries, we follow the
CC 'Brno' nomenclature for histone modifications, with positions referring
CC to those used in the literature for the 'closest' model organism. Due
CC to slight variations in histone sequences between organisms and to the
CC presence of initiator methionine in UniProtKB/Swiss-Prot sequences, the
CC actual positions of modified amino acids in the sequence generally
CC differ. In this entry the following conventions are used: H3K4me =
CC methylated Lys-5; H3K9ac = acetylated Lys-10; H3K9me = methylated Lys-
CC 10; H3S10ph = phosphorylated Ser-11; H3T11ph = phosphorylated Thr-12;
CC H3K14ac = acetylated Lys-15; H3K18ac = acetylated Lys-19; H3K18me =
CC methylated Lys-19; H3K23ac = acetylated Lys-24; H3K23me = methylated
CC Lys-24; H3K27me = methylated Lys-28; H3S28ph = phosphorylated Ser-29;
CC H3K36me = methylated Lys-37. {ECO:0000305}.
