    Functioni

    Histone methyltransferase that specifically methylates histone H3 to form H3K79me. This methylation is required for telomere silencing and for the pachytene checkpoint during the meiotic cell cycle by allowing the recruitment of RAD9 to double strand breaks. Nucleosomes are preferred as substrate compared to free histones.UniRule annotation

    Catalytic activityi

    S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone].UniRule annotation

    Enzyme regulationi

    Ubiquitination of histone H2B to form H2BK123ub1 is required for efficient DOT1 methyltransferase activity on histone H3.UniRule annotation
