Identification
NameHistone-lysine N-methyltransferase, H3 lysine-79 specific
Synonyms
  • Disrupter of telomere silencing protein 1
  • Histone H3-K79 methyltransferase
  • H3-K79-HMTase
  • Lysine N-methyltransferase 4
Gene NameDOT1
Enzyme Class
Biological Properties
General FunctionInvolved in histone-lysine N-methyltransferase activity
Specific FunctionHistone 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. Can bind to DNA (in vitro)
