abstract：:Transit from the nuclear complex to the cytoplasm through the nuclear pore complex permits modification of mRNA, including processing such as splicing, capping, and polyadenylation, etc. At each of these events, mRNA interacts with various proteins to form mRNA-protein complex. Visualizing the mRNA is crucial for unde...
