Protein

Histone-lysine N-methyltransferase set-25

Organism

Caenorhabditis elegans

Length

714 amino acids

Function

Histone methyltransferase that specifically trimethylates 'Lys-9' of histone H3 using mono- and dimethylated H3 'Lys-9' as substrate (PubMed:22939621). Acts redundantly with the methyltransferase met-2 to position chromosome arms at the nuclear lamina (PubMed:22939621). Required for small-RNA-induced H3K9 methylation (PubMed:26365259). Together with met-2, protects and stabilizes repeat-rich genomic regions by suppressing transcription-induced replication stress through methylation of H3K9 (PubMed:27668659).

Similarity

Belongs to the class V-like SAM-binding methyltransferase superfamily. Histone-lysine methyltransferase family.
