Efficient and accurate gene expression requires the coordination of multiple steps along the pathway of mRNA and protein synthesis. Now, Harel-Sharvit et al. (2010) show that transcriptional imprinting of mRNAs with two subunits of RNA polymerase II, Rbp4p and Rpb7p, guides transcripts to the translation apparatus.
高效且精确的基因表达需要沿着 mRNA 和蛋白质合成途径的多个步骤进行协调。现在,Harel-Sharvit 等人(2010)表明,RNA 聚合酶 II 的两个亚基 Rbp4p 和 Rpb7p 对 mRNA 的转录印迹指导转录本到达翻译装置。
