WebChromomethyltransferase CMT2, along with DMT DRM2, is responsible for methylation of CNN sites in the Arabidopsis genome [7]. On the phylogenetic tree of chromomethylases, methyltransferase CMT2 forms a separate branch. In most organs, the CMT2 gene is expressed much more weakly than CMT3. WebMar 24, 2016 · CHROMOMETHYLTRANSFERASE 2 (CMT2) (1). Two main lines of evidence suggest that DNA methylation plays an important role in the transcriptional silencing of transposable elements (TEs): that TEs are usually methylated, and that the loss of DNA methylation (e.g. in methyltransferase mutants) is often ...
