General annotation (Comments)
| Function | Histone methyltransferase that specifically mono- and dimethylates 'Lys-9' of histone H3 (H3K9me1 and H3K9me2, respectively) in euchromatin. H3K9me represents a specific tag for epigenetic transcriptional repression by recruiting HP1 proteins to methylated histones. Also weakly methylates 'Lys-27' of histone H3 (H3K27me). Also required for DNA methylation, the histone methyltransferase activity is not required for DNA methylation, suggesting that these 2 activities function independently. Probably targeted to histone H3 by different DNA-binding proteins like E2F6, MGA, MAX and/or DP1. During G0 phase, it probably contributes to silencing of MYC- and E2F-responsive genes, suggesting a role in G0/G1 transition in cell cycle. In addition to the histone methyltransferase activity, also methylates non-histone proteins: mediates dimethylation of 'Lys-373' of p53/TP53. Ref.1 Ref.4 |
| Catalytic activity | S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone]. Ref.1 |
| Enzyme regulation | Methyltransferase activity is inhibited by BIX-01294. Efficiently inhibited by compound E72, a BIX-01294 derivative in which the diazepane ring and the benzyl are replaced with a 3-dimethylaminopropyl and a 5-aminopentyl group at sites B and C, respectively By similarity. |
| Subunit structure | Interacts with WIZ. Part of the E2F6.com-1 complex in G0 phase composed of E2F6, MGA, MAX, TFDP1, CBX3, BAT8, EHMT1, RING1, RNF2, MBLR, L3MBTL2 and YAF2. Interacts with MPHOSPH8 By similarity. Heterodimer; heterodimerizes with EHMT2. Interacts (via ANK repeats) with RELA (when monomethylated at 'Lys-310'). Ref.1 Ref.5 |
| Subcellular location | Nucleus. Chromosome. Note: Associates with euchromatic regions. Ref.1 |
| Tissue specificity | Ubiquitous. Ref.1 |
| Domain | The ANK repeats specifically recognize and bind H3K9me1 and H3K9me2 By similarity. They also specifically recognize and bind RELA subunit of NF-kappa-B, when RELA is monomethylated at 'Lys-310'. Ref.5 The SET domain mediates interaction with WIZ By similarity. Ref.5 |
| Disruption phenotype | Embryos die around E9.5. Levels of H3K9me1 and H3K9me2 are drastically reduced. Ref.1 |
| Sequence similarities | Belongs to the histone-lysine methyltransferase family. Contains 8 ANK repeats. Contains 1 pre-SET domain. Contains 1 SET domain. |
| Sequence caution | The sequence CAM22112.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
