Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables DNA (cytosine-5-)-methyltransferase activity, acting on CpG substrates. Involved in piRNA-mediated retrotransposon silencing by heterochromatin formation. Acts upstream of or within homologous chromosome pairing at meiosis and retrotransposon silencing by DNA methylation-dependent heterochromatin formation. Predicted to be active in nucleus.
