WebAug 19, 2024 · CHROMOMETHYLASE3 (CMT3) is a plant-specific DNA methyltransferase responsible for catalyzing DNA methylation at the CHG (H = A, T, C) context. Here, we identified a positive role of CMT3 in heat … WebMar 17, 2024 · It is now known that the CMT3 protein is involved in a self-reinforcing feedback loop: CMT3 recognizes the histone mark H3K9me2 (histone H3 lysine 9 dimethylation) and then de novo methylates nearby cytosines predominantly in the CHG context but also occasionally in the CG context.
WebThree types of DNA methyltransferases (DNMTs) have been identified in plants, namely chromomethylase (CMT), methyltransferase (MET), and domain-rearranged methyltransferase (DRM) ( Cao and Jacobsen, 2002b; Ronemus et … WebJul 25, 2016 · In angiosperms, cytosine DNA methylation occurs in three sequence contexts: Methylated CG (mCG) is catalyzed by METHYLTRANSFERASE 1 (MET1), mCHG (where H is A/C/T) by CHROMOMETHYLASE 3 (CMT3), and mCHH by DOMAINS REARRANGED METHYLTRANSFERASE 2 (DRM2) or CHROMOMETHYLASE 2 (CMT2) ().MET1 …
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 … WebMay 21, 2024 · The protein structure of the maize CMT3 homologue CHROMOMETHYLASE 1 (MET2A) demonstrated that its bromo-adjacent homology …
WebCHROMOMETHYLASE 3, CMT3: Description : Encodes a chromomethylase involved in methylating cytosine residues at non-CG sites. Involved in preferentially methylating transposon-related sequences, reducing their mobility.
