RL Biochem. Biophys. Res. Commun. 404:1016-1022(2011).
CC -!- FUNCTION: Histone methyltransferase that specifically methylates
CC histone H3 to form H3K79me. This methylation is required for telomere
CC silencing, correct growth and development, and for resistance to DNA
CC damage induced by UV LIGHT. {ECO:0000269|PubMed:21187070}.
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 homocysteine; Xref=Rhea:RHEA:60328, Rhea:RHEA-COMP:15549, Rhea:RHEA-

CC ChEBI:CHEBI:59789, ChEBI:CHEBI:61961; EC=2.1.1.360;
CC Evidence={ECO:0000250|UniProtKB:Q04089, ECO:0000255|PROSITE-
CC ProRule:PRU00902};
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q04089}.
CC -!- DEVELOPMENTAL STAGE: Expressed during the whole life cycle.
CC {ECO:0000269|PubMed:21187070}.
CC -!- DISRUPTION PHENOTYPE: Individuals exhibit 4-5 hours delay in
CC development. Development does progress with fewer fruiting bodies and
CC smaller spore heads. No apparent changes in cell cycle regulation.
CC {ECO:0000269|PubMed:21187070}.
CC -!- MISCELLANEOUS: In contrast to other lysine histone methyltransferases,
CC it does not contain a SET domain, suggesting the existence of another
CC mechanism for methylation of lysine residues of histones.
CC {ECO:0000303|PubMed:21187070}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. DOT1 family. {ECO:0000255|PROSITE-ProRule:PRU00902}.
