Herein we describe the first simple and short method for specific labeling of mono- and trimethylated dinucleotide mRNA cap analogues with (13)C and (14)C isotopes. The labels were introduced within the cap structures either at the N7 for monomethylguanosine cap or N7 and N2 position for trimethylguanosine cap. The compounds designed for structural and biochemical studies will be useful tools for better understanding the role of the mRNA cap structures in pre-mRNA splicing, nucleocytoplasmic transport, translation initiation and mRNA degradation.
在此,我们描述了一种简单而快捷的方法,可将单甲基化和三甲基化二核苷酸 mRNA 帽类似物进行(13)C 和(14)C 同位素特异性标记。标记物被引入到单鸟苷酸帽的 N7 位或三鸟苷酸帽的 N7 和 N2 位。这些为结构和生化研究而设计的化合物将成为更好地理解 mRNA 帽结构在 pre-mRNA 剪接、核质转运、翻译起始和 mRNA 降解中的作用的有用工具。
