Protein

Histone-lysine N-methyltransferase, H3 lysine-79 specific

Gene

PGUG_04903

Organism
Meyerozyma guilliermondii (strain ATCC 6260 / CBS 566 / DSM 6381 / JCM 1539 / NBRC 10279 / NRRL Y-324) (Yeast) (Candida guilliermondii)
Status
Unreviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

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
