Background

Function：Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3. 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 (PubMed:12869583, PubMed:27237050, PubMed:39096901). Required for HUSH-mediated heterochromatin formation and gene silencing. Forms a complex with MBD1 and ATF7IP that represses transcription and couples DNA methylation and histone 'Lys-9' trimethylation (PubMed:14536086, PubMed:27732843). Its activity is dependent on MBD1 and is heritably maintained through DNA replication by being recruited by CAF-1 (PubMed:14536086). 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). Required to maintain a transcriptionally repressive state of genes in undifferentiated embryonic stem cells (ESCs) (PubMed:24623306). In ESCs, in collaboration with TRIM28, is also required for H3K9me3 and silencing of endogenous and introduced retroviruses in a DNA-methylation independent-pathway (By similarity). 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)

Subcellular Localization：Nucleus; Cytoplasm; Chromosome

Expression：
Tissue_specificity:Widely expressed. Highly expressed in the testes.

Isoforms & Post-Translational Modification：Q15047 has 3 isomers: Q15047-1: 143157 Da (predicted); Q15047-2: 44689 Da (predicted); Q15047-3: 143001 Da (predicted).
Degraded by the proteasome, shielded by interaction with ATF7IP;Monoubiquitinated at Lys-867 by E2 enzymes of the UBE2E family. The conjugated-Ub is protected from deubiquitination by the SET domain. Monoubiquitination at Lys-867 is required for catalytic activity, H3K9 methylation and endogenous retrovirus silencing

Subunit：Part of a complex containing at least CDYL, REST, WIZ, SETDB1, EHMT1 and EHMT2 (PubMed:19061646). Forms a complex with ATRX, TRIM28 and ZNF274 (PubMed:27029610).
