SETDB1 also contains tudor and methyl-CpG-binding domains, which may coordinate binding to methylated histones and methylated DNA, respectively (1). SETDB1 methylates histone H3 Lys9, creating a transcriptionally repressive mark that facilitates gene silencing (1-3). However, unlike SUV39H histone H3 Lys9 methyltransferases, which function mainly in heterochromatin regions, such as pericentric heterochromatin, SETDB1 functions mainly in euchromatic regions to repress gene promoters (3). SETDB1 interacts with a variety of proteins, including transcription factors (ERG), histone deacetylases (HDAC1\/2), DNA methyltransferases (DNMT3A\/B) and transcriptional co-repressors (mSin3A\/B, MBD1, KAP-1, the ATFa-associated modulator mAM) (1-6). mAM forms a complex with SETDB1, stimulating its methyltransferase activity, specifically the conversion of di-methyl to tri-methyl histone H3 Lys9 (2). MBD1 recruits SETDB1 to the CAF-1 complex to facilitate methylation of histone H3 Lys9 during replication-coupled chromatin assembly in S phase (5). DNMT3A recruits SETDB1 to silenced promoters in cancer cells (7). SETDB1 may play a role in the pathogenesis of Huntington's disease, since levels of SETDB1 protein and tri-methyl histone H3 Lys9 are both increased in diseased brains (8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nERG-associated protein with a SET domain, ESET; ERG-associated protein with SET domain; ESET; H3-K9-HMTase 4; H3-K9-HMTase4; Histone H3-K9 methyltransferase 4; Histone-lysine N-methyltransferase SETDB1; histone-lysine N-methyltransferase, H3lysine-9 specific 4; KG1T; KIAA0067; KMT1E; Lysine N-methyltransferase 1E; SET domain bifurcated 1; SET domain bifurcated histone lysine methyltransferase 1; SET domain, bifurcated 1; SETB1; SETDB1; TDRD21; tudor domain containing 21\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 180\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799519580329,"sku":"45389T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-45389t","provider":"Iright","version":"1.0","type":"link"}
