CC -!- FUNCTION: Histone methyltransferase that specifically trimethylates
CC histone H3 to form H3K79me3. This methylation is required for telomere
CC silencing and for the pachytene checkpoint during the meiotic cell
CC cycle by allowing the recruitment of RAD9 to double strand breaks.
CC Nucleosomes are preferred as substrate compared to free histone.
CC {ECO:0000256|ARBA:ARBA00003482, ECO:0000256|PIRNR:PIRNR017570}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-lysyl(79)-[histone H3] + 3 S-adenosyl-L-methionine = 3 H(+)
CC + N(6),N(6),N(6)-trimethyl-L-lysyl(79)-[histone H3] + 3 S-adenosyl-L-

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123,
CC ECO:0000256|PIRNR:PIRNR017570}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. DOT1 family. {ECO:0000256|PIRNR:PIRNR017570}.
