Function

[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.^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

SET7/9 is a protein lysine methyltransferase that methylates histone H3 and nonhistone proteins such as p53, TAF10 and oestrogen receptor alpha. In previous work, novel inhibitors of SET7/9 that are amine analogues of the coenzyme S-(5'-adenosyl)-L-methionine (AdoMet) have been developed. Here, crystal structures of SET7/9 are reported in complexes with two AdoMet analogues, designated DAAM-3 and AAM-1, in which an n-hexylaminoethyl group or an n-hexyl group is attached to the N atom that replaces the S atom of AdoMet, respectively. In both structures, the inhibitors bind to the coenzyme-binding site and their additional alkyl chain binds in the lysine-access channel. The N atom in the azaalkyl chain of DAAM-3 is located at almost the same position as the N-methyl C atom of the methylated lysine side chain in the substrate-peptide complex structures and stabilizes complex formation by hydrogen bonding to the substrate-binding site residues of SET7/9. On the other hand, the alkyl chain of AAM-1, which is a weaker inhibitor than DAAM-3, binds in the lysine-access channel only through hydrophobic and van der Waals interactions. Unexpectedly, the substrate-binding site of SET7/9 complexed with AAM-1 specifically interacts with the artificial N-terminal sequence of an adjacent symmetry-related molecule, presumably stabilizing the alkyl chain of AAM-1.
