General annotation (Comments)
| Function | Histone methyltransferase that specifically trimethylates 'Lys-20' of histone H4. H4 'Lys-20' trimethylation represents a specific tag for epigenetic transcriptional repression. Mainly functions in pericentric heterochromatin regions, thereby playing a central role in the establishment of constitutive heterochromatin in these regions. SUV420H1 is targeted to histone H3 via its interaction with RB1 family proteins (RB1, RBL1 and RBL2) By similarity. |
| Catalytic activity | S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone]. |
| Subunit structure | Interacts with HP1 proteins CBX1, CBX3 and CBX5. Interacts with RB1 family proteins RB1, RBL1 and RBL2 By similarity. |
| Subcellular location | Nucleus. Chromosome By similarity. Note: Associated with pericentric heterochromatin. CBX1 and CBX5 are required for the localization to pericentric heterochromatin By similarity. |
| Sequence similarities | Belongs to the histone-lysine methyltransferase family. Suvar4-20 subfamily. Contains 1 SET domain. |
