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: Monoubiquitinated by the UBC2-BRE1 complex to form H2BK123ub1.
CC       H2BK123ub1 gives a specific tag for epigenetic transcriptional
CC       activation and is also prerequisite for H3K4me and H3K79me formation.
CC       H2BK123ub1 also modulates the formation of double-strand breaks during
CC       meiosis and is a prerequisite for DNA-damage checkpoint activation (By
CC       similarity). {ECO:0000250}.
CC   -!- PTM: Phosphorylated by STE20 to form H2BS10ph during progression
CC       through meiotic prophase. May be correlated with chromosome
CC       condensation (By similarity). {ECO:0000250}.
CC   -!- PTM: Acetylated by GCN5 to form H2BK11ac and H2BK16ac. H2BK16ac can
CC       also be formed by ESA1. Acetylation of N-terminal lysines and
CC       particularly formation of H2BK11acK16ac has a positive effect on
CC       transcription (By similarity). {ECO:0000250}.
CC   -!- PTM: Sumoylation to form H2BK6su or H2BK7su, and probably also H2BK16su
CC       or H2BK17su, occurs preferentially near the telomeres and represses
CC       gene transcription. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the histone H2B 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: H2BK6ac =
CC       acetylated Lys-7; H2BK6su = sumoylated Lys-7; H2BK7ac = acetylated Lys-
CC       8; H2BK7su = sumoylated Lys-8; H2BS10ph = phosphorylated Ser-11;
CC       H2BK11ac = acetylated Lys-12; H2BK16ac = acetylated Lys-17; H2BK16su =
CC       sumoylated Lys-17; H2BK17su = sumoylated Lys-18; H2BK123ub1 =
CC       monoubiquitinated Lys-124. {ECO:0000305}.
