MicroRNAs regulate gene expression in numerous biological pathways and are typically methylated at their 3'-termini in plants but not in animals. Here we show that the HEN1 RNA 2'-O-methyltransferase from Arabidopsis thaliana catalyzes the transfer of extended propargylic moieties from synthetic AdoMet cofactor analogs to duplex miRNAs or siRNAs. The presented approach permits selective and efficient covalent labeling of small RNA duplexes with a variety of functional or reporter groups for their enrichment and analysis.

使用 HEN1 甲基转移酶选择性共价标记 miRNA 和 siRNA 双链体

MicroRNA 在许多生物途径中调节基因表达,并且通常在植物中的 3'-末端被甲基化,但在动物中则不然。在这里我们展示了来自拟南芥的 HEN1 RNA 2'-O-甲基转移酶催化扩展的炔丙基部分从合成的 AdoMet 辅因子类似物转移到双链体 miRNA 或 siRNA。所提出的方法允许对具有各种功能或报告基团的小 RNA 双链体进行选择性和有效的共价标记,以进行富集和分析。
