May regulate the activity of PPP4C at centrosomal microtubule organizing centers. The PPP4C-PPP4R2-PPP4R3A PP4 complex specifically dephosphorylates H2AFX phosphorylated on 'Ser-140' (gamma-H2AFX) generated during DNA replication and required for DNA DSB repair. {ECO:0000269|PubMed:18614045}. |SMK-1| |microtubule organizing center| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp6|Bortezomib 0.005μM R00 exp6]]|-3.31| |[[:results:exp75|MK-1775 0.32μM R02 exp75]]|-3.01| |[[:results:exp103|Taxol 0.004μM R03 exp103]]|-2.57| |[[:results:exp514|Phorbol-12-myristate-13-acetate 0.57μM R08 exp514]]|-2.27| |[[:results:exp60|Vinblastine 0.002μM R01 exp60]]|-2.24| |[[:results:exp175|3-Bromopyruvate 7μM R04 exp175]]|-2.17| |[[:results:exp95|BI-2536 0.0042μM R03 exp95]]|-2.15| |[[:results:exp462|Cadmium 60μM R08 exp462]]|-2.04| |[[:results:exp231|Epothilone-B 0.0015μM R05 exp231]]|-2| |[[:results:exp1|5-Fluorouracil 2μM R00 exp1]]|-1.89| |[[:results:exp216|Erlotinib 10μM R05 exp216]]|-1.87| |[[:results:exp21|MLN-4924 0.2μM R00 exp21]]|-1.81| |[[:results:exp301|VER-155008 3.9μM R06 exp301]]|1.71| |[[:results:exp282|Fluvastatin 2.2μM R06 exp282]]|2.05| |[[:results:exp443|SNS-032 15μM R08 exp443]]|2.07| |[[:results:exp80|RO-3307 4.7μM R02 exp80]]|2.3| |[[:results:exp34|Rotenone 20μM R00 exp34]]|2.34| |[[:results:exp357|Dorsomorphin 5μM R07 exp357]]|2.44| |[[:results:exp365|I-BRD9 4μM R07 exp365]]|2.46| |[[:results:exp264|Arsenate 40μM R06 exp264]]|2.73| |[[:results:exp502|Milciclib 2μM R08 exp502]]|3.41| |[[:results:exp485|GSK626616 14μM R08 exp485]]|4.35| ^Gene^Correlation^ |[[:human genes:p:ppp4c|PPP4C]]|0.438| |[[:human genes:k:kctd5|KCTD5]]|0.41| |[[:human genes:n:n6amt1|N6AMT1]]|0.405| Global Fraction of Cell Lines Where Essential: 1/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 9923 * **Expression level (log2 read counts)**: 7.29 {{:chemogenomics:nalm6 dist.png?nolink |}}
