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   -!- SIMILARITY: Belongs to the histone H4 family. {ECO:0000305}.
