CC -!- FUNCTION: Histone methyltransferase that specifically trimethylates
CC 'Lys-9' of histone H3 using monomethylated H3 'Lys-9' as substrate. H3
CC 'Lys-9' trimethylation represents a specific tag for epigenetic
CC transcriptional repression by recruiting HP1 (CBX1, CBX3 and/or CBX5)
CC proteins to methylated histones. Mainly functions in heterochromatin
CC regions, thereby playing a central role in the establishment of
CC constitutive heterochromatin at pericentric and telomere regions. H3
CC 'Lys-9' trimethylation is also required to direct DNA methylation at
CC pericentric repeats. SUV39H1 is targeted to histone H3 via its
CC interaction with RB1 and is involved in many processes (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-lysyl(9)-[histone H3] + 3 S-adenosyl-L-methionine = 3 H(+) +
CC N(6),N(6),N(6)-trimethyl-L-lysyl(9)-[histone H3] + 3 S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:60276, Rhea:RHEA-COMP:15538, Rhea:RHEA-

CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00912};
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Chromosome, centromere
CC {ECO:0000250}. Note=Associates with centromeric constitutive
CC heterochromatin. {ECO:0000250}.
CC -!- DOMAIN: Although the SET domain contains the active site of enzymatic
CC activity, both pre-SET and post-SET domains are required for
CC methyltransferase activity. The SET domain also participates in stable
CC binding to heterochromatin (By similarity). {ECO:0000250}.
CC -!- DOMAIN: In the pre-SET domain, Cys residues bind 3 zinc ions that are
CC arranged in a triangular cluster; some of these Cys residues contribute
CC to the binding of two zinc ions within the cluster. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class V-like SAM-binding methyltransferase
CC superfamily. Histone-lysine methyltransferase family. Suvar3-9
CC subfamily. {ECO:0000255|PROSITE-ProRule:PRU00912}.
