CC -!- FUNCTION: Histone methyltransferase that specifically trimethylates
CC 'Lys-9' of histone H3. H3 'Lys-9' trimethylation represents a specific
CC tag for epigenetic transcriptional repression by recruiting HP1 (CBX1,
CC CBX3 and/or CBX5) proteins to methylated histones. Mainly functions in
CC euchromatin regions, thereby playing a central role in the silencing of
CC euchromatic genes. H3 'Lys-9' trimethylation is coordinated with DNA
CC methylation. Plays a role in promoter hypermethylation and
CC transcriptional silencing of tumor suppressor genes (TSGs) or other
CC tumor-related genes. Also required to maintain a transcriptionally
CC repressive state of genes in undifferentiated embryonic stem cells
CC (ESCs). Associates at promoter regions of tumor suppressor genes (TSGs)
CC leading to their gene silencing (By similarity).
CC {ECO:0000250|UniProtKB:Q15047}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-lysyl(4)-[histone H3] + 3 S-adenosyl-L-methionine = 3 H(+) +
CC N(6),N(6),N(6)-trimethyl-L-lysyl(4)-[histone H3] + 3 S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:60260, Rhea:RHEA-COMP:15537, Rhea:RHEA-

CC ChEBI:CHEBI:59789, ChEBI:CHEBI:61961; EC=2.1.1.354;
CC Evidence={ECO:0000250|UniProtKB:Q15047, ECO:0000255|PROSITE-
CC ProRule:PRU00906};
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Chromosome {ECO:0000250}.
CC Note=Associated with non-pericentromeric regions of chromatin. Excluded
CC from nucleoli and islands of condensed chromatin (By similarity).
CC {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:PRU00190}.
