SET7/9 Protein Crystal

Background

Histone-lysine N-methyltransferase SETD7 belongs to histone methyltransferase that specifically monomethylates 'Lys-4' of histone H3. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. It plays a central role in the transcriptional activation of genes such as collagenase or insulin. It can be recruited by IPF1/PDX-1 to the insulin promoter, leading to activate transcription. SETD7 has also methyltransferase activity toward non-histone proteins such as p53/TP53, TAF10, Monomethylates 'Lys-372' of p53/TP53, stabilizing p53/TP53 and increasing p53/TP53-mediated transcriptional activation.
