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. 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).
Subunit Structure: Part of a complex containing at least CDYL, REST, WIZ, SETB1, EHMT1 and EHMT2 (PubMed:19061646). During DNA replication, it is recruited by SETDB1 to form a S phase-specific complex that facilitates methylation of H3 'Lys-9' during replication-coupled chromatin assembly and is at least composed of the CAF-1 subunit CHAF1A, MBD1 and SETDB1 (PubMed:15327775). Probably part of a corepressor complex containing ZNF304, TRIM28, SETDB1 and DNMT1 (PubMed:24623306). Interacts with TRIM28/TIF1B (PubMed:11959841). Interacts with ATF7IP and ATF7IP2; the interaction with ATF7IP is required to stimulate histone methyltransferase activity and facilitate the conversion of dimethylated to trimethylated H3 'Lys-9' (PubMed:14536086, PubMed:15691849). Interacts with MBD1; interaction is abolished when MBD1 is sumoylated (PubMed:15327775, PubMed:17066076). Interacts with CBX1 and CBX5 (PubMed:15899859). Interacts with DNMT3A and DNMT3B (PubMed:16682412). Interacts with SUMO2. Interacts with CHD7, NLK1 and PPARG (PubMed:17952062). Interacts with MPHOSPH8 (PubMed:20871592). Interacts with ERG (By similarity). Interacts with HDAC1, HDAC2, SIN3A and SIN3B (By similarity). Interacts with ATRX. Forms a complex with ATRX, TRIM28 and ZNF274 (PubMed:27029610).
Similarity: The pre-SET, SET and post-SET domains are all required for methyltransferase activity. The 347-amino-acid insertion in the SET domain has no effect on the catalytic activity.Isoform 2 lacks all domains required for histone methyltransferase activity.In the pre-SET domain, Cys residues bind 3 zinc ions that are arranged in a triangular cluster; some of these Cys residues contribute to the binding of two zinc ions within the cluster. Belongs to the class V-like SAM-binding methyltransferase superfamily. Histone-lysine methyltransferase family. Suvar3-9 subfamily.

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]

The SETDB1 setdb1 (Catalog #AAA9602370) is an Antibody produced from Mouse and is intended for research purposes only. The product is available for immediate purchase. The SETDB1 Antibody reacts with Human, Mouse, Monkey 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), ELISA (EIA). ELISA: 1:10000 WB: 1:500-1:2000. 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, Monoclonal 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
