在细胞核中合成后,mRNA经历了对其编码蛋白的适当合成、定位以及可能的功能至关重要的各个阶段。在最近的论文中,我们发现RNA聚合酶II(Pol II)的两个亚基Rpb4p和Rpb7p与新生的转录本共同转录。这种“信使核糖核酸印记”持续整个信使核糖核酸的生命周期,是正确调节信使核糖核酸经历的所有主要阶段所必需的。本文还讨论了共转录印迹的其他可能情况。由于mRNAs可以从合成细胞转运到其他细胞,我们认为mRNA印记也可以影响接收细胞的表型。这可以被视为“基于信使核糖核酸的表观遗传学”。
Following its synthesis in the nucleus, mRNA undergoes various stages that are critical for the proper synthesis, localization and possibly functionality of its encoded protein. In recent papers, we have shown that two RNA polymerase II (Pol II) subunits, Rpb4p and Rpb7p, associate with the nascent transcript co-transcriptionally. This “mRNA imprinting” lasts throughout the mRNA lifetime and is required for proper regulation of all major stages that the mRNA undergoes. Other possible cases of co-transcriptional imprinting are discussed. Since mRNAs can be transported from the synthesizing cell to other cells, we propose that mRNA imprinting can also affect the phenotype of the receiving cell. This can be viewed as “mRNA-based epigenetics.”
