Chromomethyltransferase
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. WebThe plant DNA methyltransferases are classified into four main families—maintenance DNA methyltransferase (METI), chromomethyltransferase (CMT), domains-rearranged methyltransferase (DRM) and DNA methyltransferase homologue 2 (Dnmt2; Pavlopoulou and Kossida, 2007).

By pairing the largest collection of CHROMOMETHYLTRANSFERASE (CMT) sequences (773) and methylomes (72) across land plants and green algae we provide novel insights into … WebSep 27, 2016 · CMT enzymes interact with methylated histone H3K9, a mechanism by which repressive histone methylation and DNA methylation reinforce one another [ 3 ]. DRM2 is directed to sites of action by 24-nucleotide small RNAs in a process known as RNA-directed DNA methylation (RdDM) [ 4 ].
WebCHROMOMETHYLTRANSFERASE 2 (CMT2) pathways facilitate this re-methylation. Unlike animals, mCG (and mCHG) are robustly maintained in the male germline of plants. However, asymmetric mCHH is largely lost at pericentromeric regions of meiocytes at the onset of male reproduction5,6. After meiosis, the resulting microspores divide WebCcrM (or M.CcrMI) is an orphan DNA methyltransferase, that is involved in controlling gene expression in most Alphaproteobacteria.
