Plays a role in the rescue of stalled replication forks and checkpoint control. Binds double- stranded DNA breaks and nicks as well as single-stranded DNA. Recruits the SWI/SNF chromatin remodeling complex to E2F1- responsive promoters. Down-regulates E2F1 activity and inhibits E2F1-dependent apoptosis during G1/S transition and after DNA damage. Induces a large increase in the kinase activity of ATR (PubMed:16530042). {ECO:0000269|PubMed:10498869, ECO:0000269|PubMed:11395493, ECO:0000269|PubMed:11714696, ECO:0000269|PubMed:12697828, ECO:0000269|PubMed:15075294, ECO:0000269|PubMed:16530042}. |BRCT| |PTCB-BRCT| |mitotic DNA replication checkpoint| |male germ cell nucleus| |DNA replication checkpoint| |mitotic G2/M transition checkpoint| |condensed nuclear chromosome| |negative regulation of G2/M transition of mitotic cell cycle| |PML body| |negative regulation of cell cycle G2/M phase transition| |mitotic DNA integrity checkpoint| |spindle pole| |chromosome| |DNA integrity checkpoint| |response to ionizing radiation| |mitotic cell cycle checkpoint| |microtubule organizing center| |regulation of signal transduction by p53 class mediator| |protein C-terminus binding| |cell cycle checkpoint| |regulation of G2/M transition of mitotic cell cycle| |regulation of cell cycle G2/M phase transition| |negative regulation of mitotic cell cycle phase transition| |DNA replication| |actin cytoskeleton| |negative regulation of cell cycle phase transition| |nuclear body| |negative regulation of mitotic cell cycle| |negative regulation of cell cycle process| |regulation of mitotic cell cycle phase transition| |response to radiation| |regulation of cell cycle phase transition| |DNA repair| |negative regulation of cell cycle| |mitotic cell cycle process| |regulation of mitotic cell cycle| |mitotic cell cycle| |DNA metabolic process| |regulation of cell cycle process| |cellular response to DNA damage stimulus| |cell cycle process| |identical protein binding| |response to abiotic stimulus| |regulation of cell cycle| |cell cycle| |DNA binding| |cellular response to stress| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| |regulation of intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp401|SNS-032 25μM R07 exp401]]|-2.38| |[[:results:exp329|Hydroxyurea 100μM R07 exp329]]|-2| |[[:results:exp467|CAY10603 0.55μM R08 exp467]]|-1.95| |[[:results:exp440|Aphidicolin 0.4μM R08 exp440]]|-1.75| |[[:results:exp515|PU-H71 1μM R08 exp515]]|-1.72| |[[:results:exp310|2-Methoxyestradiol 0.55μM R07 exp310]]|1.76| |[[:results:exp11|CCCP 1μM R00 exp11]]|1.81| |[[:results:exp72|LB-100 4.1μM R02 exp72]]|2.04| |[[:results:exp123|GSK-LSD1 10μM R03 exp123]]|2.1| |[[:results:exp422|Wiskostatin 3μM R07 exp422]]|2.11| ^Gene^Correlation^ |[[:human genes:p:prim1|PRIM1]]|0.478| |[[:human genes:t:tbc1d3h|TBC1D3H]]|0.443| |[[:human genes:t:tbc1d3f|TBC1D3F]]|0.442| |[[:human genes:t:tbc1d3g|TBC1D3G]]|0.441| |[[:human genes:d:ddtl|DDTL]]|0.438| |[[:human genes:s:smg1|SMG1]]|0.438| |[[:human genes:v:vps54|VPS54]]|0.437| |[[:human genes:n:nbpf10|NBPF10]]|0.428| |[[:human genes:p:psmd11|PSMD11]]|0.423| |[[:human genes:o:orc6|ORC6]]|0.423| |[[:human genes:h:hap1|HAP1]]|0.423| |[[:human genes:t:twistnb|TWISTNB]]|0.421| |[[:human genes:c:chd4|CHD4]]|0.42| |[[:human genes:o:or11h6|OR11H6]]|0.42| |[[:human genes:n:ndc80|NDC80]]|0.416| |[[:human genes:p:psma6|PSMA6]]|0.415| |[[:human genes:t:tbc1d3|TBC1D3]]|0.415| |[[:human genes:c:cdc73|CDC73]]|0.414| |[[:human genes:t:tbc1d3c|TBC1D3C]]|0.412| |[[:human genes:z:znf106|ZNF106]]|0.412| |[[:human genes:t:tfip11|TFIP11]]|0.411| |[[:human genes:c:copa|COPA]]|0.41| |[[:human genes:a:atxn1|ATXN1]]|0.405| |[[:human genes:p:pcf11|PCF11]]|0.404| |[[:human genes:c:c14orf93|C14orf93]]|0.404| |[[:human genes:c:cbwd3|CBWD3]]|0.401| Global Fraction of Cell Lines Where Essential: 304/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|1/1| |bile duct|7/28| |blood|5/28| |bone|14/26| |breast|22/33| |central nervous system|21/56| |cervix|1/4| |colorectal|9/17| |esophagus|2/13| |fibroblast|1/1| |gastric|8/16| |kidney|11/21| |liver|12/20| |lung|30/75| |lymphocyte|5/16| |ovary|17/26| |pancreas|7/24| |peripheral nervous system|8/16| |plasma cell|3/15| |prostate|0/1| |skin|10/24| |soft tissue|2/9| |thyroid|0/2| |upper aerodigestive|7/22| |urinary tract|8/29| |uterus|5/5| == Essentiality in NALM6 == * **Essentiality Rank**: 930 * **Expression level (log2 read counts)**: 7.95 {{:chemogenomics:nalm6 dist.png?nolink |}}
