MS 2-MCP成像系统广泛用于研究活细胞中mRNA的空间分布。在这里,我们报告说,MS 2-MCP系统不稳定的一些标记的mRNA靶向它们的无义介导的mRNA衰变途径。我们介绍了一个改进的版本,它抵消了这种影响,通过增加翻译终止的标记的mRNA的效率。为酵母和哺乳动物系统开发了改进的版本。
The MS2-MCP imaging system is widely used to study mRNA spatial distribution in living cells. Here, we report that the MS2-MCP system destabilizes some tagged mRNAs by targeting them to the nonsense-mediated mRNA decay pathway. We introduce an improved version, which counteracts this effect by increasing the efficiency of translation termination of the tagged mRNAs. Improved versions were developed for both yeast and mammalian systems.
