The proteins SIR2 through SIR4 repress mulitple loci by modulating chromatin structure. Involves the compaction of chromatin fiber into a more condensed form. [[https://www.uniprot.org/uniprot/H2B1_YEAST H2B1_YEAST]] 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.<ref>PMID:11973294</ref> <ref>PMID:12152067</ref> <ref>PMID:14752010</ref> <ref>PMID:15280549</ref> <ref>PMID:15652479</ref> <ref>PMID:15970663</ref> <ref>PMID:15632126</ref> <ref>PMID:15632065</ref> <ref>PMID:16598039</ref> [[https://www.uniprot.org/uniprot/H2A2_YEAST H2A2_YEAST]] Core component of nucleosome which plays a central role in DNA double strand break (DSB) repair.
