[[http://www.uniprot.org/uniprot/SETD7_HUMAN SETD7_HUMAN]] 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.<ref>PMID:12588998</ref> <ref>PMID:15099517</ref> <ref>PMID:16141209</ref> <ref>PMID:17108971</ref> <ref>PMID:12540855</ref> <ref>PMID:15525938</ref> | |||
