Replaces conventional H3 in the nucleosome core of centromeric chromatin at the inner plate of the kinetochore (PubMed:18072184). The presence of CENPA subtly modifies the nucleosome structure and the way DNA is wrapped around the nucleosome and gives rise to protruding DNA ends that are less well-ordered and rigid compared to nucleosomes containing histone H3 (PubMed:27499292, PubMed:26878239). May serve as an epigenetic mark that propagates centromere identity through replication and cell division (PubMed:15475964, PubMed:15282608, PubMed:26878239, PubMed:20739937, PubMed:21478274). Required for recruitment and assembly of kinetochore proteins, and as a consequence required for progress through mitosis, chromosome segregation and cytokinesis (PubMed:11756469, PubMed:14667408, PubMed:18072184, PubMed:23818633, PubMed:25556658, PubMed:27499292). {ECO:0000269|PubMed:11756469, ECO:0000269|PubMed:14667408, ECO:0000269|PubMed:15282608, ECO:0000269|PubMed:15475964, ECO:0000269|PubMed:15702419, ECO:0000269|PubMed:17651496, ECO:0000269|PubMed:18072184, ECO:0000269|PubMed:19114591, ECO:0000269|PubMed:21478274, ECO:0000269|PubMed:23818633, ECO:0000269|PubMed:25556658, ECO:0000269|PubMed:26878239, ECO:0000269|PubMed:27499292, ECO:0000269|PubMed:7962047, ECO:0000269|PubMed:9024683, ECO:0000305|PubMed:20739937}. |Histone| |condensed chromosome inner kinetochore| |nuclear pericentric heterochromatin| |condensed nuclear chromosome kinetochore| |kinetochore assembly| |condensed nuclear chromosome, centromeric region| |nuclear nucleosome| |protein localization to chromosome, centromeric region| |kinetochore organization| |establishment of mitotic spindle orientation| |CENP-A containing chromatin organization| |CENP-A containing nucleosome assembly| |establishment of mitotic spindle localization| |chromatin remodeling at centromere| |establishment of spindle orientation| |centromere complex assembly| |DNA replication-independent nucleosome assembly| |DNA replication-independent nucleosome organization| |establishment of spindle localization| |nucleosomal DNA binding| |histone exchange| |spindle localization| |chromosome, centromeric region| |protein localization to chromosome| |mitotic cytokinesis| |nucleosome| |ATP-dependent chromatin remodeling| |cytoskeleton-dependent cytokinesis| |cytokinesis| |microtubule cytoskeleton organization involved in mitosis| |nucleosome assembly| |establishment of cell polarity| |chromatin assembly| |chromatin assembly or disassembly| |nucleosome organization| |chromatin remodeling| |DNA packaging| |establishment or maintenance of cell polarity| |protein-DNA complex assembly| |protein-DNA complex subunit organization| |DNA conformation change| |establishment of organelle localization| |chromatin binding| |microtubule cytoskeleton organization| |protein heterodimerization activity| |cell division| |organelle localization| |mitotic cell cycle process| |microtubule-based process| |mitotic cell cycle| |chromatin organization| |viral process| |protein localization to organelle| |organelle assembly| |symbiotic process| |interspecies interaction between organisms| |cellular protein-containing complex assembly| |cell cycle process| |chromosome organization| |cytoskeleton organization| |cell cycle| |protein-containing complex assembly| |cellular protein localization| |cellular macromolecule localization| |establishment of localization in cell| |protein-containing complex subunit organization| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp125|GSK461364A 0.005μM R03 exp125]]|-2.46| |[[:results:exp131|L-74142 5μM R03 exp131]]|-2.41| |[[:results:exp362|GSK-J4 1μM R07 exp362]]|-2.29| |[[:results:exp302|35°C R06 exp302]]|-1.87| |[[:results:exp517|Quercetin 20μM R08 exp517]]|-1.85| |[[:results:exp97|BI-6727 0.0125μM R03 exp97]]|-1.82| |[[:results:exp449|Arsenic trioxide 60μM R08 exp449]]|-1.81| ^Gene^Correlation^ |[[:human genes:c:c14orf80|C14orf80]]|0.464| |[[:human genes:g:gemin8|GEMIN8]]|0.458| |[[:human genes:t:tubd1|TUBD1]]|0.434| Global Fraction of Cell Lines Where Essential: 368/726 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|1/1| |bile duct|15/28| |blood|10/28| |bone|8/25| |breast|13/33| |central nervous system|28/56| |cervix|4/4| |colorectal|11/17| |esophagus|11/13| |fibroblast|1/1| |gastric|6/15| |kidney|8/21| |liver|7/20| |lung|43/75| |lymphocyte|8/14| |ovary|9/26| |pancreas|17/24| |peripheral nervous system|10/16| |plasma cell|9/15| |prostate|0/1| |skin|9/24| |soft tissue|2/7| |thyroid|2/2| |upper aerodigestive|18/22| |urinary tract|21/29| |uterus|3/5| == Essentiality in NALM6 == * **Essentiality Rank**: 197 * **Expression level (log2 read counts)**: 4.84 {{:chemogenomics:nalm6 dist.png?nolink |}}
