Background InformationPost -translational modification of histones, such as phosphorylation, acetylation, and methylation, are crucial for chromatin remodeling. SUV39H1 and Suv39h1 are the human and mouse homologs of Drosophila Su(var)3-9 protein, respectively. These proteins selectively methylate histone H3 at lysine 9 creating a high-affinity binding site for the HP1 proteins (heterochromatin protein 1). HP1 proteins are known to interact with transcription suppressor proteins, suggesting that the interactions with SUV39H1 and methylated histone H3 mediate a silence effect on the transcription of target genes. Furthermore, over-expression of SUV39H1 in HeLa cells causes a redistribution of endogenous HP1 proteins and growth retardation, suggesting that SUV39H1-mediated modulation of heterochromatin can impair cell cycle progression.

Entrez Gene Number
Entrez Gene SummaryThis gene is a member of the suppressor of variegation 3-9 homolog family and encodes a protein with a chromodomain and a C-terminal SET domain. This nuclear protein moves to the centromeres during mitosis and functions as a histone methyltransferase, methylating Lys-9 of histone H3. Overall, it plays a vital role in heterochromatin organization, chromosome segregation, and mitotic progression.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: O43463 # Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3 using monomethylated H3 'Lys- 9' as substrate. Also weakly methylates histone H1 (in vitro). 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 differentiaton, repression by the PML-RARA fusion protein, BMP-induced repression, repression of switch recombination to IgA and regulation of telomere length.


SIZE: 412 amino acids; 47907 Da

SUBUNIT: Interacts with H3 and H4 histones. Interacts with GFI1B, 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. In case of infection, interacts with HTLV-1 Tax protein, leading to abrogate Tax transactivation of HTLV-1 LTR.

SUBCELLULAR LOCATION: Nucleus. Note=Associates with centromeric constitutive heterochromatin.

DEVELOPMENTAL STAGE: Accumulates during mitosis at centromeres during prometaphase, but dissociates from the centromere at the meta- to anaphase transition.

DOMAIN: SwissProt: O43463 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.

PTM: Phosphorylated on serine residues, and to a lesser degree, on threonine residues. The phosphorylated form is stabilized by SBF1 and is less active in its transcriptional repressor function.


SIMILARITY: 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.
