Background
SETD7 (SET Domain Containing (Lysine Methyltransferase) 7) is a histone methyltransferase that specifically monomethylates ‘Lys-4’ of histone H3. H3 ‘Lys-4’ methylation represents a specific tag for epigenetic transcriptional activation. Plays a central role in the transcriptional activation of genes such as collagenase or insulin. Recruited by IPF1/PDX-1 to the insulin promoter, leading to activate transcription. Has also methyltransferase activity toward non-histone proteins such as p53/TP53, TAF10, and possibly TAF7 by recognizing and binding the [KR]-[STA]-K in substrate proteins. Monomethylates ‘Lys-189’ of TAF10, leading to increase the affinity of TAF10 for RNA polymerase II. Monomethylates ‘Lys-372’ of p53/TP53, stabilizing p53/TP53 and increasing p53/TP53-mediated transcriptional activation.
Application Notes
Recombinant SETD7 is suitable for use in the study of enzyme kinetics, inhibitor screening, and selectivity profiling.
HMT Assay Conditions: 1 μM H3K4me0 (1-21aa) peptide was incubated with different concentrations of recombinant SETD7 protein in reaction buffer containing 50 mM TrisCl pH 8.6, 0.02% Triton X-100, 2 mM MgCl2, 1 mM TCEP, 100 μM SAM for 2 hours at room temperature. Activity was detected by HTRF and Fluorography.

SETD7 protein was run on an 8% SDS-PAGE gel and stained with Coomassie blue.
Recombinant SETD7 protein HTRF activity assay.
1 μM H3K4me0 (1-21aa) peptide was incubated with SETD7 in reaction buffer for 2 hour at room temperature. SETD7 enzyme was used in a HTRF assay to determine enzyme linearity. Methylated peptide (H3K4me1) was measured using H3K4me1-specific antibody.
Recombinant SETD7 protein activity assay.
2 ug Calf Thymus Octamers was incubated with 0.5 ug SETD7 protein in reaction buffer containing radioactive 3H-SAM for 2 hour at room temperature. Activity was detected by fluorography.
Storage
Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.
