DOT1L Histone methyltransferase. Methylates 'Lys-79' of histone H3. Nucleosomes are preferred as substrate compared to free histones. Binds to DNA. Belongs to the class I-like SAM-binding methyltransferase superfamily. DOT1 family. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
