Background: The Erg-associated protein with SET domain (ESET), also known as SET domain, bifurcated 1 (SETDB1) protein, is a member of a family of histone lysine methyltransferases, each of which contains a conserved catalytic SET domain originally identified in Drosophila, Enhancer of zeste, and Trithorax proteins. ESET also contains tudor and methyl-CpG-binding domains, which may coordinate binding to methylated histones and methylated DNA, respectively. ESET methylates histone H3 Lys9, creating a transcriptionally repressive mark that facilitates gene silencing. However, unlike SUV39H histone H3 Lys9 methyltransferases, which function mainly in heterochromatin regions such as pericentric heterochromatin, ESET functions mainly in euchromatic regions to repress gene promoters. ESET 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). mAM forms a complex with ESET, stimulating its methyltransferase activity, specifically the conversion of di-methyl to tri-methyl histone H3 Lys9. MBD1 recruits ESET to the CAF-1 complex to facilitate methylation of histone H3 Lys9 during replication-coupled chromatin assembly in S phase. DNMT3A recruits ESET to silenced promoters in cancer cells. ESET may play a role in the pathogenesis of Huntington's disease, since levels of ESET protein and tri-methyl histone H3 Lys9 are both increased in diseased brains.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a histone methyltransferase which regulates histone methylation, gene silencing, and transcriptional repression. This gene has been identified as a target for treatment in Huntington Disease, given that gene silencing and transcription dysfunction likely play a role in the disease pathogenesis. Alternatively spliced transcript variants of this gene have been described.[provided by RefSeq, Jun 2011]
Uniprot Description
SETDB1: a protein lysine methyltransferase that specifically trimethylates K9 of histone H3 (H3K9me3), a specific tag for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Unlike SUV39H H3K9 methyltransferase, which functions mainly in heterochromatin regions such as pericentric heterochromatin, SETDB1 functions mainly in euchromatic regions, playing a central role in the silencing of euchromatic genes. H3K9me3 is coordinated with DNA methylation. 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). Its activity is dependent on MBD1 and is heritably maintained through DNA replication by being recruited by CAF-1. Contains Tudor and methyl-CpG-binding domains, which may coordinate binding to methylated histones and methylated DNA, respectively. Is targeted to histone H3 by TIF1B, a factor recruited by KRAB zinc-finger proteins. Recruited by DNMT3A to silenced promoters in cancer cells. May play a role in the pathogenesis of Huntington's disease, since levels of SETDB1 and H3K9me3 are both increased in diseased brains. Belongs to the histone-lysine methyltransferase family. Suvar3-9 subfamily. Three isoforms of the human protein are produced by alternative splicing.

Product Notes
The SETDB1 setdb1 (Catalog #AAA840596) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The SETDB1 Antibody reacts with Human, Mouse and may cross-react with other species as described in the data sheet. AAA Biotech's SETDB1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemistry (IHC), Immunoprecipitation (IP). Western blot: 1:500 - 1:1000, IHC: 1:50 - 1:100, IP: 1:50 - 1:100. Researchers should empirically determine the suitability of the SETDB1 setdb1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "SETDB1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
