General annotation (Comments)

Function	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. Also able to demethylated 'Lys-372' of p53/TP53 in vitro. Ref.6 Ref.7 Ref.8 Ref.9 Ref.14 Ref.16
Catalytic activity	S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N(6)-methyl-L-lysine.
Subunit structure	Interacts with IPF1/PDX-1. Ref.8
Subcellular location	Nucleus.
Tissue specificity	Widely expressed. Expressed in pancreatic islets.
Domain	The SET domain is necessary but not sufficient for histone methyltransferase activity.
Miscellaneous	Monomethyltransferase activity is achieved by disrupting the formation at near-attack conformations for the dimethylation reaction.
Sequence similarities	Belongs to the histone-lysine methyltransferase family. SET7 subfamily. Contains 3 MORN repeats. Contains 1 SET domain.
biophysicochemical properties	Kinetic parameters: KM=29 µM for histone H3 KM=12 µM for TAF10 KM=69 µM for TP/p53
