DNA (cytosine-5)-methyltransferase DRM2

UniProtKB accession:  Q9M548

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in de novo DNA methylation. Controls asymmetric and CpNpG methylation. Required for FWA gene silencing but not for the maintenance of SUP gene silencing. Functionally redundant to CMT3 to maintain non-CpG methylation. Involved in RNA-directed DNA methylation (RdDM) (PubMed:12121623, PubMed:12151602, PubMed:14680640). Acts as major DNA methyltransferase in the RdDM pathway, and is essential for RNA-directed de novo DNA methylation of cytosines in all sequence contexts (PubMed:21060858, PubMed:21212233). Associates with long non-coding RNA (lncRNA) produced by RNA polymerase V (Pol V). This association is dependent on AGO4 and IDN2, and results in DNA methylation of RdDM target loci (PubMed:24862207).
