Interaction of the cotranslational Hsp70 Ssb with ribosomal proteins and rRNA depends on its lid domain

In yeast, the heterodimeric ribosome-associated complex (RAC) acts in concert with the Hsp70 protein Ssb, forming a unique chaperone triad. Here the authors use structural and biochemical approaches to shed light on how translation and folding are coupled in eukaryotes.
