physiological function | the enzyme is required for the RNA-directed DNA methylation, dedicated to the methylation of target sequences, which include transposable elements, regulatory regions of several protein-coding genes, and 5S rRNA-encoding DNA arrays. Pol IV, RDR2, DRM2, and Pol V, actors of the RdDM, are required to maintain a transcriptional silencing of 5S RNA genes at chromosomes 4 and 5, regulation, overview | Arabidopsis thaliana |
