DNA methylation in Dictyostelium discoideum
(2007-03-15)
DNA methyltransferases of type Dnmt2 are a highly conserved protein family with enigmatic function. The aim of this work was to characterize DnmA, the Dnmt2 methyltransferase in Dictyostelium discoideum, and further to investigate its implication in DNA methylation and transcriptional gene silencing.
The genome of the social amoeba Dictyostelium encodes DnmA as the sole DNA methyltransferase. The enzyme bears all ten characteristic DNA methyltransferase motifs in its catalytic domain. The DnmA mRNA was found by ...
