General annotation (Comments)

Function

Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling By similarity. SAAS SAAS000558

Subunit structure

The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA By similarity. RuleBase RU000451

Subcellular location

Nucleus By similarity RuleBase RU000451.

Sequence similarities

Belongs to the histone H2B family. RuleBase RU000451
