Abstract:Signal-sequence dependent protein targeting is essential for the spatiotemporal organization of eukaryotic and prokaryotic cells and facilitated by dedicated protein targeting factors, such as the signal recognition particle (SRP). However, targeting signals are not exclusively contained within proteins, but can also be present within mRNAs. By in vivo and in vitro assays, we show that mRNA targeting is controlled by the nucleotide content and by secondary structures within mRNAs. mRNA binding to bacterial mem… Show more
