Enables several functions, including C2H2 zinc finger domain binding activity; histone-lysine N-methyltransferase activity; and promoter-specific chromatin binding activity. Involved in DNA methylation; histone methylation; and regulation of DNA replication. Acts upstream of or within several processes, including macromolecule methylation; negative regulation of autophagosome assembly; and response to cocaine. Located in nucleus. Is expressed in several structures, including alimentary system; limb; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in idiopathic pulmonary fibrosis. Orthologous to human EHMT2 (euchromatic histone lysine methyltransferase 2).
