    Dedicated chaperones protect newly synthesized ribosomal proteins (r-proteins) from aggregation and accompany them on their way to assembly into nascent ribosomes. Currently, only nine of the ∼80 eukaryotic r-proteins are known to be guarded by such chaperones. In search of new dedicated r-protein chaperones, we performed a tandem-affinity purification based screen and looked for factors...

    Nuclear import of dimerized ribosomal protein Rps3 in complex with its chaperone Yar1

    Mitterer, Valentin ; Gantenbein, Nadine ; Birner-Gruenberger, Ruth ; Murat, Guillaume ; Bergler, Helmut ; Kressler, Dieter ; Pertschy, Brigitte

    In: Scientific Reports, 2016, vol. 6, p. 36714

    After their cytoplasmic synthesis, ribosomal proteins need to be transported into the nucleus, where they assemble with ribosomal RNA into pre-ribosomal particles. Due to their physicochemical properties, they need protection from aggregation on this path. Newly synthesized ribosomal protein Rps3 forms a dimer that is associated with one molecule of its specific chaperone Yar1. Here we report...
