H3 'Lys-9' trimethylation represents a specific tag for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Mainly functions in euchromatin regions, thereby playing a central role in the silencing of euchromatic genes. H3 'Lys-9' trimethylation is coordinated with DNA methylation. Probably forms a complex with MBD1 and ATF7IP that represses transcription and couples DNA methylation and histone 'Lys-9' trimethylation. Its activity is dependent on MBD1 and is heritably maintained through DNA replication by being recruited by CAF-1. SETDB1 is targeted to histone H3 by TRIM28/TIF1B, a factor recruited by KRAB zinc-finger proteins. Probably forms a corepressor complex required for activated KRAS-mediated promoter hypermethylation and transcriptional silencing of tumor suppressor genes (TSGs) or other tumor-related genes in colorectal cancer (CRC) cells (PubMed:24623306). Also required to maintain a transcriptionally repressive state of genes in undifferentiated embryonic stem cells (ESCs) (PubMed:24623306). Associates at promoter regions of tumor suppressor genes (TSGs) leading to their gene silencing (PubMed:24623306). The SETDB1-TRIM28-ZNF274 complex may play a role in recruiting ATRX to the 3'-exons of zinc-finger coding genes with atypical chromatin signatures to establish or maintain/protect H3K9me3 at these transcriptionally active regions (PubMed:27029610). {ECO:0000269|PubMed:12869583, ECO:0000269|PubMed:14536086, ECO:0000269|PubMed:15327775, ECO:0000269|PubMed:17952062, ECO:0000269|PubMed:24623306, ECO:0000269|PubMed:27029610}. |MBD| |SET| |Pre-SET| |histone methyltransferase activity (H3-K9 specific)| |positive regulation of methylation-dependent chromatin silencing| |regulation of methylation-dependent chromatin silencing| |positive regulation of chromatin silencing| |negative regulation of single stranded viral RNA replication via double stranded DNA intermediate| |histone H3-K9 methylation| |regulation of single stranded viral RNA replication via double stranded DNA intermediate| |histone H3-K9 modification| |histone-lysine N-methyltransferase activity| |regulation of chromatin silencing| |promoter-specific chromatin binding| |negative regulation of viral genome replication| |histone lysine methylation| |negative regulation of viral life cycle| |response to vitamin| |peptidyl-lysine methylation| |histone methylation| |regulation of viral genome replication| |negative regulation of viral process| |positive regulation of chromatin organization| |chromosome| |response to ethanol| |regulation of gene silencing| |protein alkylation| |protein methylation| |regulation of viral life cycle| |positive regulation of chromosome organization| |regulation of chromatin organization| |regulation of viral process| |response to nutrient| |negative regulation of multi-organism process| |regulation of symbiosis, encompassing mutualism through parasitism| |response to alcohol| |Ras protein signal transduction| |macromolecule methylation| |response to antibiotic| |methylation| |peptidyl-lysine modification| |small GTPase mediated signal transduction| |regulation of chromosome organization| |histone modification| |covalent chromatin modification| |chromatin binding| |response to nutrient levels| |response to toxic substance| |response to extracellular stimulus| |positive regulation of organelle organization| |intracellular membrane-bounded organelle| |chromatin organization| |regulation of multi-organism process| |zinc ion binding| |peptidyl-amino acid modification| |response to drug| |chromosome organization| |positive regulation of cellular component organization| |regulation of organelle organization| |DNA binding| |response to oxygen-containing compound| |intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp75|MK-1775 0.32μM R02 exp75]]|-1.77| |[[:results:exp499|LY2090314 0.003μM R08 exp499]]|1.74| |[[:results:exp21|MLN-4924 0.2μM R00 exp21]]|1.77| |[[:results:exp379|MSC2530818 10μM R07 exp379]]|2.04| |[[:results:exp67|BVD-523 15μM R02 exp67]]|2.16| |[[:results:exp460|BML-284 0.09μM R08 exp460]]|2.41| |[[:results:exp357|Dorsomorphin 5μM R07 exp357]]|2.74| |[[:results:exp59|UMK57 1μM R01 exp59]]|3.14| |[[:results:exp312|2-Methoxyestradiol 0.55 to 1μM on day4 R07 exp312]]|3.48| |[[:results:exp106|UM131593 0.2μM R03 exp106]]|5.91| ^Gene^Correlation^ |[[:human genes:a:atf7ip|ATF7IP]]|0.538| |[[:human genes:i:id3|ID3]]|0.504| |[[:human genes:c:cbx3|CBX3]]|0.495| |[[:human genes:t:trim28|TRIM28]]|0.479| |[[:human genes:a:atat1|ATAT1]]|0.471| |[[:human genes:z:znf592|ZNF592]]|0.463| |[[:human genes:b:brpf1|BRPF1]]|0.458| |[[:human genes:e:ehmt2|EHMT2]]|0.458| |[[:human genes:a:arl14ep|ARL14EP]]|0.439| |[[:human genes:n:nsd1|NSD1]]|0.434| |[[:human genes:m:mllt1|MLLT1]]|0.429| |[[:human genes:a:aff1|AFF1]]|0.428| |[[:human genes:d:ddx5|DDX5]]|0.418| |[[:human genes:c:ccdc101|CCDC101]]|0.408| |[[:human genes:t:taf5l|TAF5L]]|0.406| |[[:human genes:a:ambra1|AMBRA1]]|0.404| Global Fraction of Cell Lines Where Essential: 69/726 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|2/28| |blood|9/28| |bone|7/25| |breast|1/33| |central nervous system|1/56| |cervix|0/4| |colorectal|3/17| |esophagus|4/13| |fibroblast|0/1| |gastric|1/15| |kidney|1/21| |liver|2/20| |lung|5/75| |lymphocyte|0/14| |ovary|2/26| |pancreas|2/24| |peripheral nervous system|2/16| |plasma cell|3/15| |prostate|1/1| |skin|0/24| |soft tissue|0/7| |thyroid|0/2| |upper aerodigestive|4/22| |urinary tract|3/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1249 * **Expression level (log2 read counts)**: 6.48 {{:chemogenomics:nalm6 dist.png?nolink |}}
