A method for visualizing the location and movement of a specific RNA of interest in a living cell, in real time, is disclosed. The method includes the following steps: (a) providing a DNA encoding the RNA, which RNA includes a protein-binding site; (b) providing a nucleic acid encoding a fusion protein, which fusion protein comprises a fluorescent domain and an RNA-binding domain; (c) introducing the DNA encoding the RNA, and the nucleic acid encoding the fusion protein, into a eukaryotic cell so that the DNA encoding the RNA and the nucleic acid encoding the fusion protein are expressed in the cell; and (d) detecting fluorescence outside the nucleus or inside the nucleus of the cell, with the fluorescence being from the fusion protein bound to the RNA. In some embodiments, the fusion protein also includes an intracellular localization domain.
