Overview

Product name

Anti-KMT1E / SETDB1 antibody
See all KMT1E / SETDB1 products (6) ...

Description

Rabbit polyclonal to KMT1E / SETDB1

Specificity

Detects a band at 170kD in 293 cell lysate. This band can be blocked by the immunising peptide in WB. The predicted size is 143kD, however, several other antibodies detect bands at the same size as ab5430.

Applications

Our Abpromise guarantee covers the use of ab5430 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Target

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.

Predicted band size : 143 kDa


Western blot using ab5430 at 1/1000 on 293 cell lysate. 30µg of lysate per lane. Peptide competition (not shown) blocks staining of this band. Predicted size is 143kD, but other antibodies also show staining at about 170kD.

Immunocytochemistry/ Immunofluorescence - KMT1E / SETDB1 antibody (ab5430)

ICC/IF image of ab5430 stained HepG2 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab5430, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
