Synchronizing Nuclear Import of Ribosomal Proteins with Ribosome Assembly
Copyright policy )Synchronizing Nuclear Import of Ribosomal Proteins with Ribosome Assembly
Symportin Synchrony Ribosomes, the macromolecular machines responsible for protein synthesis, function in the cytoplasm but are assembled in the nucleus. Ribosomal proteins must be imported into the nucleus, but how this is coordinated with assembly is unclear. Kressler et al. (p. 666 ) report that two 5S rRNA binding proteins are coimported into the nucleus. They identify a transport adaptor, which they term symportin (Syo1), that binds simultaneously to Rpl5 and Rpl11. Syo1 also interacts with the import receptor Kap104, which facilitates import of the Syo1-Rpl5-Rpl11 complex. Synchronous nuclear transport may be more generally used to coordinate assembly processes.
