Human Histone H2B Type 2-E, HIST2H2BE ELI

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.
