General annotation (Comments)
| Function | Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3 using monomethylated H3 'Lys-9' as substrate. H3 'Lys-9' trimethylation represents a specific tag for epigenetic transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5) proteins to methylated histones. Mainly functions in heterochromatin regions, thereby playing a central role in the establishment of constitutive heterochromatin at pericentric and telomere regions. H3 'Lys-9' trimethylation is also required to direct DNA methylation at pericentric repeats. SUV39H1 is targeted to histone H3 via its interaction with RB1 and is involved in many processes, such as cell cycle regulation, transcriptional repression and regulation of telomere length. May participate in regulation of higher-order chromatin organization during spermatogenesis. Ref.7 |
| Catalytic activity | S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone]. |
| Subunit structure | Interacts with SMAD5. Ref.8 |
| Subcellular location | Nucleus By similarity. Chromosome › centromere By similarity. Note: Associates with centromeric constitutive heterochromatin By similarity. |
| Domain | Although the SET domain contains the active site of enzymatic activity, both pre-SET and post-SET domains are required for methyltransferase activity. The SET domain also participates to stable binding to heterochromatin By similarity. |
| Sequence similarities | Belongs to the histone-lysine methyltransferase family. Suvar3-9 subfamily. Contains 1 chromo domain. Contains 1 post-SET domain. Contains 1 pre-SET domain. Contains 1 SET domain. |
