Chromomethylase 3 cmt3
WebDec 10, 2002 · The CMT3 class of genes are specific to the plant kingdom and encode methyltransferase proteins containing a chromo domain ( 28 ). CMT3 loss-of-function mutants were isolated in three independent studies, and show a genome-wide loss of CpNpG methylation and a reduction of asymmetric methylation at some loci ( 24, 29, 30 ). WebHere, we report that microRNA-mediated repression of CHROMOMETHYLASE 3 (CMT3) and the chromatin features that CMT3 prefers help prevent ectopic methylation of thousands of genes during embryogenesis that can persist for weeks afterwards. Moreover, CMT3-induced ectopic methylation of genes undergoing transcriptional activation can reduce …
