  • 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.
  • Tissue specificity
    Widely expressed. High expression in testis.
  • Sequence similarities
    Belongs to the histone-lysine methyltransferase family. Suvar3-9 subfamily.
    Contains 1 MBD (methyl-CpG-binding) domain.
    Contains 1 post-SET domain.
    Contains 1 pre-SET domain.
    Contains 1 SET domain.
    Contains 2 Tudor domains.
  • Domain
    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.
  • Cellular localization
    Nucleus. Chromosome. Associated with non-pericentromeric regions of chromatin. Excluded from nucleoli and islands of condensed chromatin.

  • Samples: Whole cell lysate (10 mcg for 3 and 4; 50 mcg for 1 and 2) from 293T cells that were mock transfected (1 and 2) or transfected with a SETDB1 expression construct (3 and 4).
  • ab12317 (4ug/ml) staining KMT1E in human testis using an automated system (DAKO Autostainer Plus). Using this protocol there is strong staining of KMT1E in nuclear compartments of the germinal epithelium.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
  • Whole cell lysate (2 mg) from 293T cells that were mock transfected (1 and 2) or transfected with a SETDB1 expression construct (3 and 4). Rabbit anti-SETDB1 antibodies; ab12317 (2 and 4) and a competitor's antiserum (1 and 3) were used at 1 mcg/mg lysate for IP. ab12317 was used at 0.2 mcg/ml for Western Blot. Detection: Chemiluminescence with exposure times of 1 to 5 minutes.

Thanks for your enquiry. There are two western blots on the datasheet for ab12317. I believe you are referring to the bottom image. I think there is a mistake in the annotation for this blot. 'Mock transfected' should refer to lanes 3 and 4 of this blot, not lanes 1 and 2. I am sorry for the confusion here. I hope this information helps to explain things. Please feel free to contact me again with any further questions.

Thank you for your enquiry. The predicted molecular weight of SETDB1 is 155kDa, based on the amino acid composition of the protein. It should be noted however that this protein is known to be phophorylated, as indicated on the Swissprot data page entry for SETDB1 under the 'Sequence annotation (Features)' section: http://www.uniprot.org/uniprot/Q15047 Phosphorylation of a protein will slow its migration through a gel, making it appear much heavier than normal. This may be what you are seeing. Alternatively, sometimes proteins run a little slower than expected based on their amino acid composition, even without post translational modifications. This may be what is happening here. Similar results are seen with ab12317, another antibody to SETDB1. ab12317 detects a band of 170kDa via western blotting. I hope this is helpful. Feel free to send me an image of your blot and I'll be happy to look at it.  Please contact me again if you have any further questions.
