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.<ref>PMID:11859126</ref> <ref>PMID:12860195</ref> <ref>PMID:15019208</ref> Has broad antibacterial activity. May contribute to the formation of the functional antimicrobial barrier of the colonic epithelium, and to the bactericidal activity of amniotic fluid.<ref>PMID:11859126</ref> <ref>PMID:12860195</ref> <ref>PMID:15019208</ref> | ||
