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. Required for checkpoint-mediated arrest of cell cycle progression in response to low doses of ionizing radiation and for efficient repair of DNA double strand breaks (DSBs) specifically when modified by C- terminal phosphorylation. {ECO:0000269|PubMed:10959836, ECO:0000269|PubMed:12419185, ECO:0000269|PubMed:12607005, ECO:0000269|PubMed:15201865}. |Histone| |XY body| |male germ cell nucleus| |site of DNA damage| |replication fork| |condensed nuclear chromosome| |cellular response to gamma radiation| |cellular senescence| |chromosome, telomeric region| |response to gamma radiation| |damaged DNA binding| |site of double-strand break| |double-strand break repair via nonhomologous end joining| |cell aging| |non-recombinational repair| |positive regulation of DNA repair| |nucleosome| |cellular response to ionizing radiation| |double-strand break repair via homologous recombination| |positive regulation of response to DNA damage stimulus| |recombinational repair| |cerebral cortex development| |nucleosome assembly| |regulation of DNA repair| |histone binding| |DNA damage checkpoint| |chromatin assembly| |DNA integrity checkpoint| |response to ionizing radiation| |chromatin assembly or disassembly| |nucleosome organization| |pallium development| |cellular response to radiation| |DNA packaging| |double-strand break repair| |cell cycle checkpoint| |positive regulation of DNA metabolic process| |protein-DNA complex assembly| |regulation of response to DNA damage stimulus| |DNA recombination| |meiotic cell cycle| |nuclear chromatin| |protein-DNA complex subunit organization| |telencephalon development| |aging| |DNA conformation change| |cellular response to abiotic stimulus| |cellular response to environmental stimulus| |enzyme binding| |regulation of DNA metabolic process| |forebrain development| |nuclear speck| |response to radiation| |protein heterodimerization activity| |centrosome| |DNA repair| |spermatogenesis| |male gamete generation| |negative regulation of cell cycle| |gamete generation| |chromatin organization| |viral process| |regulation of cellular response to stress| |brain development| |DNA metabolic process| |cellular response to DNA damage stimulus| |head development| |symbiotic process| |interspecies interaction between organisms| |multicellular organismal reproductive process| |sexual reproduction| |cellular protein-containing complex assembly| |multicellular organism reproduction| |central nervous system development| |multi-organism reproductive process| |chromosome organization| |response to abiotic stimulus| |regulation of cell cycle| |cell cycle| |reproductive process| |reproduction| |DNA binding| |regulation of response to stress| |protein-containing complex assembly| |cellular response to stress| |protein-containing complex subunit organization| |positive regulation of nucleobase-containing compound metabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp299|Talazoparib 0.006μM R06 exp299]]|-3| |[[:results:exp360|Genistein 15μM R07 exp360]]|-2.79| |[[:results:exp520|Rucaparib 6.5μM R08 exp520]]|-2.73| |[[:results:exp512|Olaparib 4μM R08 exp512]]|-1.85| |[[:results:exp300|VE-822 0.04μM R06 exp300]]|-1.82| |[[:results:exp77|Prochlorperazine 5.2μM R02 exp77]]|-1.79| |[[:results:exp13|Chloramphenicol 20μM R00 exp13]]|1.71| ^Gene^Correlation^ |[[:human genes:r:rnf168|RNF168]]|0.515| |[[:human genes:s:swsap1|SWSAP1]]|0.462| |[[:human genes:s:spidr|SPIDR]]|0.449| Global Fraction of Cell Lines Where Essential: 44/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|2/28| |bone|2/26| |breast|4/33| |central nervous system|2/56| |cervix|1/4| |colorectal|0/17| |esophagus|1/13| |fibroblast|0/1| |gastric|1/16| |kidney|3/21| |liver|3/20| |lung|1/75| |lymphocyte|2/16| |ovary|4/26| |pancreas|1/24| |peripheral nervous system|1/16| |plasma cell|0/15| |prostate|0/1| |skin|1/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|2/22| |urinary tract|4/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1288 * **Expression level (log2 read counts)**: 6.37 {{:chemogenomics:nalm6 dist.png?nolink |}}
