[[http://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> [[http://www.uniprot.org/uniprot/CHZ1_YEAST CHZ1_YEAST]] Forms a chaperone-bound H2A.Z-H2B complex that acts as a source for SWR1 complex-dependent H2A to H2A.Z histone replacement in chromatin.<ref>PMID:17289584</ref>

[https://www.uniprot.org/uniprot/H2AZ_YEAST H2AZ_YEAST] Variant histone H2A which can replace H2A in some nucleosomes. 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. This variant is enriched at promoters, it may keep them in a repressed state until the appropriate activation signal is received (PubMed:11000274, PubMed:11081628, PubMed:11090616, PubMed:11509669, PubMed:12628191, PubMed:14645854, PubMed:14690608, PubMed:15045029, PubMed:16239142, PubMed:16344463, PubMed:16543223). Near telomeres, it may counteract gene silencing caused by the spread of heterochromatin proteins (PubMed:16543222). Required for the RNA polymerase II and SPT15/TBP recruitment to the target genes (PubMed:11509669). Involved in chromosome stability (PubMed:15353583). Required to target MPS3 to the inner membrane of the nuclear envelope (PubMed:21518795).<ref>PMID:11000274</ref> <ref>PMID:11081628</ref> <ref>PMID:11090616</ref> <ref>PMID:11509669</ref> <ref>PMID:12628191</ref> <ref>PMID:14645854</ref> <ref>PMID:14690608</ref> <ref>PMID:15045029</ref> <ref>PMID:15353583</ref> <ref>PMID:16239142</ref> <ref>PMID:16344463</ref> <ref>PMID:16543222</ref> <ref>PMID:16543223</ref> <ref>PMID:21518795</ref> [https://www.uniprot.org/uniprot/H2B1_YEAST H2B1_YEAST] Core component of nucleosome.
