Drosophila melanogaster genomic DNA sequence homologous to mammalian cytosine DNA-methyltransferase gene.
Using Southern blotting procedure we have shown that Drosophila genomic DNA hybridizes with 4423-bp C-terminal fragment of murine cytosine DNA-methyltransferase gene. Thus, the Drosophila genome has a sequence homologous to the mammalian cytosine DNA-methyltransferase gene. We assume that DNA methylation most likely responsible for strong CpG suppression in the Drosophila genome mainly was catalyzed by a cytosine DNA-methyltransferase that has since been lost.
