EOG8N8TK2 GO:0005634 7/13 nucleus cellular_component "A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent."

[ISBN:0198506732] EOG8N8TK2 GO:0018024 1/13 histone-lysine N-methyltransferase activity molecular_function "Catalysis of the reaction: S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N6-methyl-L-lysine. The methylation of peptidyl-lysine in histones forms N6-methyl-L-lysine, N6,N6-dimethyl-L-lysine and N6,N6,N6-trimethyl-L-lysine derivatives." [EC:2.1.1.43, RESID:AA0074, RESID:AA0075, RESID:AA0076]
