Protein: Histone-lysine N-methyltransferase, H3 lysine-79 specific (A0A8M3AXT4)
Organism: Danio rerio (Zebrafish) (Brachydanio rerio)
Function: Histone methyltransferase that specifically trimethylates histone H3 to form H3K79me3. 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 histone
Subcellular location: Nucleus
InterPro domains:
- IPR030445: Histone H3-K79 methyltransferase (family) [4-581]
- IPR025789: Histone-lysine N-methyltransferase DOT1 domain (domain) [16-330]
- IPR029063: S-adenosyl-L-methionine-dependent methyltransferase superfamily (homologous_superfamily) [6-344]
