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 repression of MYOD1-stimulated differentiation, regulation of the control switch for exiting the cell cycle and entering differentiation, repression by the PML-RARA fusion protein, BMP-induced repression, repression of switch recombination to IgA and regulation of telomere length. Component of the eNoSC (energy-dependent nucleolar silencing) complex, a complex that mediates silencing of rDNA in response to intracellular energy status and acts by recruiting histone-modifying enzymes. The eNoSC complex is able to sense the energy status of cell: upon glucose starvation, elevation of NAD+/NADP+ ratio activates SIRT1, leading to histone H3 deacetylation followed by dimethylation of H3 at 'Lys-9' (H3K9me2) by SUV39H1 and the formation of silent chromatin in the rDNA locus. Ref.8 Ref.10 Ref.11 Ref.12 Ref.13 Ref.14 |
| Catalytic activity | S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone]. Ref.7 |
| Enzyme regulation | Negatively regulated by KIAA1967/DBC1 By similarity. |
| Subunit structure | Interacts with KIAA1967/DBC1 and GFI1B. Component of the eNoSC complex, composed of SIRT1, SUV39H1 and RRP8 By similarity. Interacts with H3 and H4 histones. Interacts with DNMT3B, CBX1, CBX4, MBD1, RUNX1, RUNX3, MYOD1, SMAD5 and RB1. Interacts with SBF1 through the SET domain. Interacts with HDAC1 and HDAC2 through the N-terminus and associates with the core histone deacetylase complex composed of HDAC1, HDAC2, RBBP4 and RBBP7. Interacts (via SET domain) with MECOM; enhances MECOM transcriptional repression activity. Ref.1 Ref.9 Ref.10 Ref.15 |
| Subcellular location | Nucleus. Chromosome › centromere. Note: Associates with centromeric constitutive heterochromatin. Ref.1 Ref.14 |
| Tissue specificity | |
| Developmental stage | Expression present throughout embryogenesis. Higher expression between E9.5 and E13. |
| 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. |
| Post-translational modification | Phosphorylated on serine residues, and to a lesser degree, on threonine residues By similarity. Acetylated at Lys-266, leading to inhibition of enzyme activity. SIRT1-mediated deacetylation relieves this inhibition By similarity. |
| Disruption phenotype | Mice lacking Suv39h1 and Suv39h2 display severely impaired viability and chromosomal instabilities that are associated with an increased tumor risk and perturbed chromosome interactions during male meiosis. They also show a higher level of histone H3 with phosphorylated 'Ser-10' and a reduced number of cells in G1 phase and an increased portion of cells with aberrant nuclear morphologies. Ref.8 |
| 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. |
| Sequence caution | Isoform 2: The sequence AAF60970.1 differs from that shown. Reason: Frameshift at position 35. |
