WebDRM2 introduces methyl groups onto C residues in DNA when it has been targeted to a region of DNA by an AGO complex so that the 24-nt siRNA is, in effect, the determinant of genomic regions that are to be methylated by DRM2. The involvement of DNA methylation gives this pathway an epigenetic property.

WebThe direct UVR8-DRM2 interaction ( Figs. 4 and 5) and inhibition of DRM2-mediated DNA methylation by UVR8 ( Figs. 1 and 2) suggest that UVR8 might negatively regulates DRM2. To dissect the molecular mechanism, we first determined whether UVR8 regulates DRM2 protein stability. WebDNA methylation is a modification of the DNA base cytosine and is often associated with transcriptional repression. In plants, the RNA-directed DNA methylation (RdDM) pathway is required for establishment of de novo DNA methylation ( 1, 2 ), catalyzed by DOMAINS REARRANGED METHYLTRANSFERASE 2 (DRM2).
